In case you haven’t heard, Twitter is getting a whole new look. After rolling out the redesigned profile pages to a small number of users, Twitter is beginning to update its entire user base—a move it had promised weeks ago.
So what are the new sizes? Everything is explained below.
- Header Photo: 1500 pixels wide x 500 pixels high, 5MB file size limit
This is the main image across the top of the screen. Twitter recommends 1500×500 pixels but the header photo will always blow-up to be screen-wide, which means a 1500×500 image can look very poor on a 30-inch monitor unless it’s saved at a very high resolution.
I would suggest uploading a 3000×1000 photo or save your 1500×500 image at the highest possible dots per inch (DPI) you can you manage to squeeze it under the 5 megapixel limit.
- Your Profile Photo (or Avatar): 400×400 pixels minimum, 2MB file size limit
Twitter recommends a 400×400 minimum here, and the image should be a square (although you can crop during the upload). Again, I recommend saving to as high a DPI as you can – I believe the maximum file size is 2MB although this is no longer specified by Twitter.
The profile photo scales down to 200×200 on your profile page, gets even smaller in timelines, and blows up to full size when somebody clicks on it, so make sure your image looks clear at all scales.
- Background Image: This is no longer required!
Twitter has essentially phased out background images with this update. While they still show up in certain places as you’re navigating Twitter (at least for now) this is something only you will see, and they’re not visible on your actual profile page by other users.
Really, there’s no point wasting time creating an amazing background image that nobody is going to see. I would suggest going to your profile design settings and setting a solid background colour instead.
