Facebook Image Sizes

With 1.18 billion monthly active users, Facebook is the world’s largest social network. One bad image choice could spell the difference in attracting and engaging with this huge user base and being completely ignored.

One thing to remember when choosing your photos is that there is a difference between how things will display on your personal timeline and how things will display in a user’s news feed. Make sure that you are choosing dimensions based on where you want the majority of viewers to see your image.

Profile Picture: 180 x 180 (Displays 170 x 170 on Desktop)

Say cheese: this is going to be the photo representing you or your brand on Facebook. This is the square photo that appears on your timeline layered over your cover photo. Your profile picture will also appear when you post to other walls, comment on posts or when your profile is searched.

Image Guidelines

• Must be at least 180 x 180 pixels.
• Photo will appear on page as 170 x 170 pixels on desktop and 128 x 128 on smartphones.
• Profile pictures are located 16 pixels from the left and 176 pixels from the top of your cover photo on desktop.
• Profile pictures are located 24 pixels from the left, 24 pixels from the bottom and 196 pixels from the top of your cover photo on smartphones.
• Photo thumbnail will appear throughout Facebook at 32 x 32 pixels.

Business Page Profile Picture: 180 x 180 (Displays 170 x 170 on Desktop)

Facebook recently changed its Profile image for Business Pages to appear to the left side of the screen. The new look helps Facebook Business Pages stand out among personal accounts. However, the dimensions are the same, but the photo appears on the page slightly different.

Image Guidelines

• Must be at least 180 x 180 pixels.
• Photo will appear on page as 170 x 170 pixels on desktop, 128 x 128 on smartphones, and 36 x 36 on most feature phones.
• Photo thumbnail will appear throughout Facebook at 32 x 32 pixels.
• Business Page images will be cropped to fit a square.

Cover Photo: 820 x 312

Your Facebook cover photo will only appear on your Facebook timeline, but it is a lot bigger than the profile picture, which gives you more freedom to choose something creative. Where your profile picture might be a good choice for a picture of you, or a brand logo, use this space to post something that speaks more toward you as an individual or as a brand.

Image Guidelines

• Appear on page at 820 x 312 pixels. Anything less will be stretched.
• Minimum size of 400 x 150 pixels.
• Displays at 820 x 312 pixels on desktop and 640 x 360 pixels on smartphones.
• For best results, upload an sRGB JPG file less than 100 KB.
• Images with a logo or text may be best as a PNG file.
• Business Page dimensions are exactly the same as personal accounts.

Shared Image: 1,200 x 630

A shared image is one of the most common forms of sharing on Facebook. These images will always appear on your timeline, and ideally they will show up in most of your followers’ News Feeds — though with the decrease in organic reach, it’s unlikely that everyone will see your post. The more people engage with your post, the more likely it is that the rest of your followers and their followers will see that activity.

Image Guidelines

• Recommended upload size of 1,200 x 630 pixels.
• Will appear in feed at a max width of 470 pixels (will scale to a max of 1:1).
• Will appear on page at a max width of 504 pixels (will scale to a max of 1:1).

Shared Link: 1200 x 628

Another great tool in your Facebook belt is the ability to share a link. It’s very similar to posting a shared image, but it gives you even more fields to work with. You can choose to create a shared link with a small square image to the left and text on the right, or with a larger rectangular image on top with text underneath.

Image Guidelines

• Recommended upload size of 1,200 x 628 pixels.
• Square Photo: Minimum 154 x 154px in feed.
• Square Photo: Minimum 116 x 116 on page.
• Rectangular Photo: Minimum 470 x 246 pixels in feed.
• Rectangular Photo: Minimum 484 x 252 on page.
• Facebook will scale photos under the minimum dimensions. For better results, increase image resolution at the same scale as the minimum size.

Event Image: 1920 x 1005 (Recommended)

Facebook Events help capture the attention of users and cut through the noise on Facebook. Reminders are sent to your audience and having a good space with an even better image is important. Make sure you have the right dimensions down for a Facebook Event cover photo.

Image Guidelines

• Facebook will scale down to minimum dimensions: 470 × 174.
• Shows in feed: 470 × 174.

Fundraiser image: 800 x 300 (recommended)

Facebook has added the ability to create a fundraiser for charitable organizations or personal causes. The cover photo for these fundraisers slightly varies from a typical Facebook cover photo, with a minimum size of 400 x 150. The best experience across many display types will come from a higher resolution image, though.

Twitter Image Sizes

Don’t let its logo fool you–Twitter is not just for the birds. In fact, with 313 million monthly active users, Twitter is one of the social media networks that your customers will most often use to discuss your brand. And recently, Twitter made some big changes to its overall layout.

Profile Photo: 400 x 400 (Displays 200 x 200)

Your Twitter profile photo is the main image that represents you or your brand across the network. It’s going to be seen across the site in a number of places by a number of people so make sure it’s of the highest quality. Here’s the places your profile photo will be visible on the site.

• On Your Page: The largest display of your profile picture is on your homepage and can be viewed by your followers as well as individuals who stumble upon your page.
• In-Stream: A smaller version of your profile picture appears in a follower’s Twitter stream every time you Tweet. It also appears in the stream of your followers’ followers every time you’re Retweeted.
• Who to Follow: Your profile picture is also going to appear next to a link to your page in the “Who to follow” box. This is located directly to the right of your twitter stream. Choose a recognizable image here.

Image Guidelines

• Square Image recommended 400 x 400 pixels.
• Maximum file size 5 MB.
• Image types include: JPG, GIF or PNG.

Header Photo: 1,500 x 500

Your header photo is the image that spans the top of your Twitter profile page. It’s quite a bit larger than your profile photo so make sure to save it at the highest resolution possible. Because you have more room to be creative with this picture and it will likely be the first thing your visitors see, make it something captivating.

Image Guidelines

• Recommended 1,500 x 500 pixels.
• Maximum file size of 5 MB.
• Image types include: JPG, GIF or PNG.

In-Stream Photos and Shared Links

Twitter users can attach photos to any of their Tweets. Depending on whether you’re attaching one photo, multiple, or sharing a link, the way photos crop and display in stream will vary slightly.

Fortunately, in 2021, Twitter made waves with #Twittercropisgone, eliminating the sometimes-unfavorable automated cropping for vertical images that had often become the subject of memes and in-jokes among users of the platform. Extremely wide or tall images with unusual dimensions may still get cropped, but for most images in standard 4:3 or 16:9 dimensions (or close to them), you won’t have to worry as much about centering subjects around automated cropping. https://platform.twitter.com/embed/Tweet.html?dnt=true&embedId=twitter-widget-0&features=eyJ0ZndfZXhwZXJpbWVudHNfY29va2llX2V4cGlyYXRpb24iOnsiYnVja2V0IjoxMjA5NjAwLCJ2ZXJzaW9uIjpudWxsfSwidGZ3X2hvcml6b25fdHdlZXRfZW1iZWRfOTU1NSI6eyJidWNrZXQiOiJodGUiLCJ2ZXJzaW9uIjpudWxsfSwidGZ3X3NwYWNlX2NhcmQiOnsiYnVja2V0Ijoib2ZmIiwidmVyc2lvbiI6bnVsbH19&frame=false&hideCard=false&hideThread=false&id=1390026628957417473&lang=en&origin=https%3A%2F%2Fsproutsocial.com%2Finsights%2Fsocial-media-image-sizes-guide%2F&sessionId=71b283bf197c3b452a96a741b52e9d0453471d13&theme=light&widgetsVersion=9fd78d5%3A1638479056965&width=550px

The following are some best practices to get an optimal result, and you can also preview the end result in Sprout’s Compose window before you publish.

Recommended sizes for images by types of Tweets:

• Image from a Tweet with shared link: 1200 x 628 pixels

Pinterest Image Sizes

Pinterest can be an amazing social tool for driving referral traffic to your site. This is mostly due to the fact that 90% of Pinterest pages are external links.

So it’s very important for you to make sure you’re optimizing your Pinterest page regularly and using proper image sizes for your boards and pins.

Profile Picture: 165 x 165

When setting up your Pinterest account you have the option to do so using Facebook, Twitter or email. If you choose Facebook or Twitter, Pinterest will pull in the profile image that you have set there.

If you’re using email, or would prefer to use a different photo, you can do that too: just upload a square photograph (the larger the better) and Pinterest will resize it to fit. Like other social sites your profile picture on Pinterest should be something closely tied to you or your brand.

Image Guidelines

• Recommended size: 165 x 165 pixels
• Maximum 10 MB.
• Image types include: JPG and PNG for profile pictures.

Pin Sizes

When adding a pin to your board, it’s important to remember that Pinterest puts a limit on the width of the image but not the length. This gives you the opportunity to add a photo that’s square or one that will scale to be even taller. Just remember to make sure you’re creating large images because they add more value, not just because you can.

Image Guidelines

• It’s recommended to use an image aspect ratio of 2:3 to 1:3.5
• Expanded pins have a minimum width 600 pixels, so to maintain aspect ratio, 900 px is the recommended height.

Board Display

Creating boards is one of the most important things that you can do on Pinterest. It’s important to make sure you’re using an image that fits the size criteria perfectly. Not only is it important to choose a photo that is enticing to your audience, it’s important to choose one that’s relevant to that particular board.

Image Guidelines

• 222 x 150 pixels (large thumbnail)
• 55 x 55 (smaller thumbnail)

Find more information in the Pinterest Help Center.

YouTube Image Sizes

YouTube has more than 1 billion unique users every month and is available on hundreds of millions of devices. More than 1 million brands have already realized that YouTube is a great opportunity to reach their fan-base.

Channel Profile Image: 800 x 800

YouTube allows you to select different profile image borders, but the dimensions stay the same. Ensure your YouTube has a profile image set up before you select your border.

Image Guidelines:

• Recommended 800 x 800 pixels.
• Image types: JPG, GIF, BMP or PNG.

Channel Cover Photo: 2,048 x 1,152

• Safe area for mobile and web (without text and logo cropping) 1546 x 423 pixels.

Find more information in the YouTube Help Center.

Video Uploads: 1280 x 720 (Minimum HD)

This video is mainly about different techniques about how to use SSH tunneling serving and maintaining access when not possible .

i am actually adding this video particularly because of the graphic approach followed explaining how communication in the internet work , more precisely , IP PORTS .

Types of Port Forwarding

SSH’s port forwarding feature can smuggle various types of Internet traffic into or out of a network. This can be used to avoid network monitoring or sniffers, or bypass badly configured routers on the Internet. Note: You might also need to change the settings in other programs (like your web browser) in order to circumvent these filters.

There are three types of port forwarding with SSH:

• Local port forwarding: connections from the SSH client are forwarded via the SSH server, then to a destination server
• Remote port forwarding: connections from the SSH server are forwarded via the SSH client, then to a destination server
• Dynamic port forwarding: connections from various programs are forwarded via the SSH client, then via the SSH server, and finally to several destination servers

Local port forwarding is the most common type. For example, local port forwarding lets you bypass a company firewall that blocks Wikipedia.

Remote port forwarding is less common. For example, remote port forwarding lets you connect from your SSH server to a computer on your company’s intranet.

Dynamic port forwarding is rarely used. For example, dynamic port forwarding lets you bypass a company firewall that blocks web access altogether. Although this is very powerful, it takes a lot of work to set up, and it’s usually easier to use local port forwarding for the specific sites you want to access.

Port-forwarding is a widely supported technique and a feature found in all major SSH clients and servers, although not all clients do it the same way. For help on using a specific client, consult the client’s documentation. For example, the PuTTY manual has a section on port forwarding in PuTTY.

To use port forwarding, you need to make sure port forwarding is enabled in your server. You also need to tell your client the source and destination port numbers to use. If you’re using local or remote forwarding, you need to tell your client the destination server. If you’re using dynamic port forwarding, you need to configure your programs to use a SOCKS proxy server. Again, exactly how to do this depends on which SSH client you use, so you may need to consult your documentation.

Local Port Forwarding

Local port forwarding lets you connect from your local computer to another server. To use local port forwarding, you need to know your destination server, and two port numbers. You should already know your destination server, and for basic uses of port forwarding, you can usually use the port numbers in Wikipedia’s list of TCP and UDP port numbers.

For example, say you wanted to connect from your laptop to http://www.ubuntuforums.org using an SSH tunnel. You would use source port number 8080 (the alternate http port), destination port 80 (the http port), and destination server www.ubuntuforums.org. :

ssh -L 8080:www.ubuntuforums.org:80 <host>

Where <host> should be replaced by the name of your laptop. The -L option specifies local port forwarding. For the duration of the SSH session, pointing your browser at http://localhost:8080/ would send you to http://www.ubuntuforums.org/.

In the above example, we used port 8080 for the source port. Ports numbers less than 1024 or greater than 49151 are reserved for the system, and some programs will only work with specific source ports, but otherwise you can use any source port number. For example, you could do:

ssh -L 8080:www.ubuntuforums.org:80 -L 12345:ubuntu.com:80 <host>

This would forward two connections, one to www.ubuntuforums.org, the other to www.ubuntu.com. Pointing your browser at http://localhost:8080/ would download pages from www.ubuntuforums.org, and pointing your browser to http://localhost:12345/ would download pages from www.ubuntu.com.

The destination server can even be the same as the SSH server. For example, you could do:

ssh -L 5900:localhost:5900 <host>

This would forward connections to the shared desktop on your SSH server (if one had been set up). Connecting an SSH client to localhost port 5900 would show the desktop for that computer. The word “localhost” is the computer equivalent of the word “yourself”, so the SSH server on your laptop will understand what you mean, whatever the computer’s actual name.

Remote Port Forwarding

Remote port forwarding lets you connect from the remote SSH server to another server. To use remote port forwarding, you need to know your destination server, and two port numbers. You should already know your destination server, and for basic uses of port forwarding, you can usually use the port numbers in Wikipedia’s list of TCP and UDP port numbers.

For example, say you wanted to let a friend access your remote desktop, using the command-line SSH client. You would use port number 5900 (the first VNC port), and destination server localhost:

ssh -R 5900:localhost:5900 guest@joes-pc

The -R option specifies remote port forwarding. For the duration of the SSH session, Joe would be able to access your desktop by connecting a VNC client to port 5900 on his computer (if you had set up a shared desktop).

Dynamic Port Forwarding

Dynamic port forwarding turns your SSH client into a SOCKS proxy server. SOCKS is a little-known but widely-implemented protocol for programs to request any Internet connection through a proxy server. Each program that uses the proxy server needs to be configured specifically, and reconfigured when you stop using the proxy server.

For example, say you wanted Firefox to connect to every web page through your SSH server. First you would use dynamic port forwarding with the default SOCKS port:

ssh -C -D 1080 laptop

The -D option specifies dynamic port forwarding. 1080 is the standard SOCKS port. Although you can use any port number, some programs will only work if you use 1080. -C enables compression, which speeds the tunnel up when proxying mainly text-based information (like web browsing), but can slow it down when proxying binary information (like downloading files).

Next you would tell Firefox to use your proxy:

• go to Edit -> Preferences -> Advanced -> Network -> Connection -> Settings…
• check “Manual proxy configuration”
• make sure “Use this proxy server for all protocols” is cleared
• clear “HTTP Proxy”, “SSL Proxy”, “FTP Proxy”, and “Gopher Proxy” fields
• enter “127.0.0.1” for “SOCKS Host”
• enter “1080” (or whatever port you chose) for Port.

You can also set Firefox to use the DNS through that proxy, so even your DNS lookups are secure:

• Type in about:config in the Firefox address bar
• Find the key called “network.proxy.socks_remote_dns” and set it to true

The SOCKS proxy will stop working when you close your SSH session. You will need to change these settings back to normal in order for Firefox to work again.

To make other programs use your SSH proxy server, you will need to configure each program in a similar way.
