X photo sizes and image limits
X does not publish one magic pixel size for every photo. A dated table of display sizes and file limits, labeled official or reported. Compression is next door.

X doesn't publish one magic pixel size for every photo. Use a dated table of display sizes and file limits, and label each row official or reported. Compression and how many photos fit in one post already have their own answers. Re-check current X Help. Leave video specs alone.
What photo sizes does X display?
X does not publish one official pixel size that fits every photo in the timeline, on a profile, and in a header.
A search for "X image sizes" on 9 November 2026, America/Los_Angeles, returned a top set that included picturesizes.com's X image size guide, tendX's X image sizes page, and Hootsuite's multi-network size guide (dated November 2026). Rank order in that set was not stable: this guide saw picturesizes.com first, and a separate SEO check saw tendX first, so this page names the set without calling any of them #1. Those pages agree on some profile and header numbers and disagree on in-feed recommendations.
| What | Figure | Label | Source | Last checked |
|---|---|---|---|---|
| Profile photo | 400 x 400 px | reported | tendX; Hootsuite November 2026 guide; picturesizes.com | 9 November 2026, America/Los_Angeles |
| Header / cover photo | 1500 x 500 px | reported | tendX; Hootsuite November 2026 guide; picturesizes.com | 9 November 2026, America/Los_Angeles |
| In-feed single image | Third parties disagree (tendX and picturesizes.com: 1200 x 675; Hootsuite: 1280 x 720 landscape) | reported | those pages | 9 November 2026, America/Los_Angeles |
| Official X Help or developer display-size page | Not re-read | official fetch failed | Live help.x.com photo pages were not usable; the developer URL did not return a usable display-size document | 9 November 2026, America/Los_Angeles |
There is no official winner among the reported in-feed numbers. Re-check current X Help, or your own composer preview, before you treat any pixel pair as official.
What file limits should you know?
Upload size, what happens after X has the file, and how many photos one tweet can have already live on Does X compress photos? (updated 7 November 2026, checked 9 November 2026, America/Los_Angeles). That answer is not copied here.
What a local agent can send is documented on What your agent can do (updated 7 November 2026, checked 9 November 2026, America/Los_Angeles): add_photo takes a JPEG, PNG, or WEBP from a path on this machine. That is the public tool list, not a substitute for X Help.
EXIF and location metadata belong on Should you remove EXIF before posting?.
Which numbers are official and which are reported?
A number is official here only if it comes from X Help or another official X page that could be read on the check date. Everything taken from tendX, Hootsuite, picturesizes.com, or another roundup is reported.
The display-size rows in the table above are reported. The official display-size row is empty on purpose, because those X pages could not be re-read today. If Help opens on the day you write, copy the current figures into your own notes and keep the label honest.
An official-versus-reported table is not claimed as a unique invention. Other guides already separate sources. The job here is to date every cell and drop any number that cannot be sourced.
Where do compression and photo-count questions go?
Compression, the upload size that avoids extra processing on the way, and how many photos one tweet can have go to Does X compress photos?. EXIF goes to Should you remove EXIF before posting?.
This page owns display sizes and the official-versus-reported cut. It will not become those answers, and it will not become a video guide. Video specs are documented separately on the video docs, not here.
How should you frame a product screenshot?
Keep the part of a screenshot that must stay readable toward the center of the frame. Reported size guides disagree about how the timeline crops the edges, so do not treat a third-party pixel pair as a safe-zone map.
Evenpost is an app for X (Twitter) for solo founders. You and your agent draft, you approve each post in the Evenpost app, and it posts with natural spacing, or right away if you choose Post now. An agent running on your own computer can attach images from a local file. A hosted connection adds them in the app. Updates: @evenpost.
Open the compression and EXIF answers before you export a screenshot, then fill the table from Help, not from memory.
