The best GIF size and frame rate for most uses is 480 to 640 pixels wide at 10 to 12 frames per second, kept to 3 to 8 seconds and under 5 MB. That's sharp enough for text, smooth enough for UI motion, and light enough to load quickly. The MobileStudio Video to GIF tool uses these defaults and fits the GIF under the size limit you pick.
The short answer
| Use | Width | Frame rate | Length | Size limit |
|---|---|---|---|---|
| GitHub README | 640 px | 10 to 12 fps | 3 to 8 s | Under 5 MB |
| Product Hunt | 640 px | 12 fps | 3 to 6 s | 5 MB |
| Slack, Teams, Discord | 480 px | 10 fps | 2 to 5 s | 1 to 5 MB |
| 320 to 480 px | 8 to 10 fps | 2 to 4 s | Under 1 MB | |
| Blog or docs page | 480 to 640 px | 10 fps | 3 to 6 s | Under 2 MB |
What frame rate should a GIF be?
10 to 12 fps for most GIFs. Video is usually 30 fps, but GIFs don't need it: 10 fps already looks smooth for screen recordings, UI animations, and reactions, at a third of the frames. Use 15 to 16 fps only for fast motion like gameplay, and 8 fps when size is tight. The tool offers 8, 10, 12, and 16 fps.
What width should a GIF be?
480 px for general use, 640 px when there's text to read, 320 px for email and tiny chat previews. Every step up in width multiplies the pixels per frame. Wider than 800 px rarely makes sense for a GIF; use a video instead.
How long should a GIF be?
3 to 8 seconds. Long enough to show one action, short enough to stay small and keep attention. The tool allows up to 10 seconds. If you need longer, switch to MP4; see GIF vs MP4.
What file size should a GIF be?
Under 5 MB for READMEs and galleries, under 1 MB for email, and as small as you can for web pages, where heavy GIFs slow everything down. GitHub warns about files over 50 MiB, as it explains in About large files on GitHub, but a README GIF should be far smaller than that.
How do I make a GIF with these settings?
- Open Video to GIF.
- Drop in your video and set the Start and Length.
- Choose the Size target, Width, and Frame rate from the table above.
- Click Create GIF.
If the GIF is over the target, the tool rebuilds it at a smaller width or frame rate automatically. For more ways to shrink it, see how to make a GIF smaller.
How many colors should a GIF have?
GIF supports up to 256 colors per frame, as the Library of Congress notes in its GIF overview. Screen recordings and flat illustrations look great with 128 to 256. Photos and gradients band at any setting; that's the format's limit, not your settings.
Why does my GIF look choppy or blurry?
- Choppy: the frame rate is too low for the motion. Try 12 or 16 fps.
- Blurry: the source was shrunk too much. Record a smaller area, or use 640 px.
- Grainy: the color palette is struggling. Shorter clips with fewer colors help, and FFmpeg's palette filters, described in the FFmpeg documentation, give cleaner results.
