indielyCheck Steam screenshot size before you upload.
Select one or more screenshots to verify their pixel dimensions and 16:9 aspect ratio. Files stay on your device and are removed from the tool when you close or refresh the page.
The checker uses the current Steamworks store asset guidance: screenshots should be 1920×1080 or larger and use a 16:9 aspect ratio.
| File | Dimensions | Ratio | Result |

Correct dimensions are the beginning, not the finish.
Show the game
Use authentic gameplay images that help players understand interaction, viewpoint and visual quality.
Build a sequence
Arrange screenshots to introduce the core loop first, then variety, progression and distinctive moments.
Check small displays
Important subjects and UI should still read when a screenshot is shown as a smaller store thumbnail.
Why 16:9 matters
A consistent aspect ratio avoids unintended cropping and makes the set feel coherent across store surfaces. This tool allows a small tolerance for rounded or exported dimensions.
Keep originals
Do not upscale a weak capture just to pass a dimension check. Capture at the highest practical quality, keep lossless source files and export a clean store-ready version.
Steam screenshot checker questions
What resolution and aspect ratio does Steam require for screenshots?
Steam requires store page screenshots to use a widescreen 16:9 aspect ratio at 1920 × 1080 pixels or higher.
How many screenshots should a Steam store page have?
Steam requires at least 5 screenshots to publish a store page. Showing 6 to 10 varied gameplay screenshots helps players understand the core loop and visual variety.
Are my screenshots uploaded to a server when I check them?
No. Image dimensions and aspect ratios are inspected directly in your browser tab and never uploaded.
