Tips & best practices
- Single tweet images display best at 16:9 (1600x900) — this aspect ratio shows the full image without cropping
- Profile photos are circular on display but upload as 400x400 square — keep your subject centered
- Header images (1500x500) may be partially hidden behind profile elements on mobile
- Use PNG for screenshots and graphics, JPEG for photographs
- Twitter compresses images aggressively — upload at higher resolution than you need for crisp display
Frequently Asked Questions
What image size should I use for tweets?
1600x900 pixels (16:9 aspect ratio) is optimal for single-image tweets. This ensures the full image displays in the timeline without any cropping on both desktop and mobile.
What is the X/Twitter header image size?
1500x500 pixels (3:1 ratio). Keep important content away from the edges as the display area varies between desktop and mobile views.
Does X compress uploaded images?
Yes. X applies compression to images over 5MB and converts PNGs to JPEG in some cases. For best quality, upload images under 5MB as PNG.
What size is a Twitter Card image?
Summary Card with Large Image uses 800x418 pixels. The standard Summary Card uses 120x120 pixels. Set these via meta tags on your website.
