The minimumTwiter image size in 2020 is 600 x 335 pixels (width x height) image.
Larger images (for example 1200 x 670) are better optimized for when users click to expand images.
Images can be as big as 15MB on twitter.com.
The aspect ratio for these iamges is 16:9. Images taller than this 16:9 proportion will be cropped in the feed on both mobile and on desktop –except for GIFs and videos, which can appear up to square.
File types: PNG, JPEG, or GIF are recommended.
Twitter does not accept BMP or TIFF files.
@mikemorrison has a number of tips on how to make https://osf.io/ef53g/, including a Twitter Poster Power Point template that you can download here - and we have a local copy here!
Prezentr also has a Twitter PowerPoint Template available here!
Even optimized PowerPoint templates will be trimmed at the edges when Twitted.
If you are interested in showcasing you work in various slides, you can use @mikemorrison's PowerPoint template given above and present your slides exporting the final presentation as GIF (instructions in the template).
An ideal GIF has about 4 to 5 slides, each lasting about 4 to 5 seconds. Beware of the slide size - content amount and size must be properly weighted!
Don't forget to save your work as a ppt* file before converting it to GIF!
