Steam Capsule Sizes 2026: Every Asset Dimension
Steam reworked its store and library asset sizes in 2024, and the numbers scattered across Steamworks documentation don't always match what you find in older blog posts and forum threads. Here's the current, verified list — and a free tool that generates every size from one source image.

The problem
A Steam store page needs a dozen-plus differently-sized image assets: header capsule, small capsule, main capsule, vertical capsule, library capsule, library header, library hero, library logo, page background, screenshots, and icons. Get one wrong and Steamworks either rejects the upload or silently crops it badly. Most "Steam capsule size" guides online are copy-pasted from each other and several predate the 2024 asset rework, so the numbers you find by Googling are often stale.
How it works
- Verify each dimension directly against Steamworks' current documentation (partner.steamgames.com/doc/store/assets) rather than trusting memory or older guides.
- Upload one source image to the Steam Capsule Resizer — it never leaves your browser.
- Drag the focal point per asset, choose fit or fill, and export PNG or JPG for each size individually.
Your image never leaves your browser. All resizing happens locally on canvas — nothing is uploaded anywhere.
When to use this tool
Use it when you're setting up a new Steam store page from scratch, when Valve reworks asset requirements again and your existing art no longer fits, or when you just need to double-check a single asset with the built-in Validator mode before uploading it to Steamworks.
