How to find an image’s dimensions
- Choose the original image.
Select a photo or screenshot, or drop it into the tool. It is read in your browser.
- Read width × height.
The result shows pixel dimensions, orientation, aspect ratio, megapixels and the file’s storage size.
- Copy the result.
Use the dimensions in your editor or compare an exported screenshot with an App Store category.
Pixels, file size and aspect ratio
Dimensions describe width and height in pixels. File size in KB or MB describes storage, not resolution. A 1920 × 1080 image has a 16:9 aspect ratio; a DPI label does not add pixels.
This checker reads an image without resizing it. To change its dimensions, use the batch image resizer.
Preparing App Store visuals?
Screenshot sizes and App Preview video resolutions are different. This tool checks still images; it does not inspect a video’s resolution, duration or codec.
Common questions
Which image formats can I check?
JPG/JPEG, PNG and WebP work in modern browsers. Other formats depend on your browser’s decoder; HEIC and RAW support is not reliable across browsers. If a file cannot be read, export a JPEG or PNG copy from your photo app first. Animated images, when readable, report their canvas dimensions. SVG dimensions describe its rendered size, not a fixed raster resolution.
Can I check an image without uploading it?
Yes. Your selected file is read locally and is not sent to a server. You can also enter width and height to calculate a ratio without choosing a file.
Is 2048 × 2732 exactly 3:4?
No. Its exact simplified ratio is 512:683. A nearby common ratio is a comparison, not an exact pixel match. Check the accepted pixel pair when preparing an App Store screenshot.
Need to add a device frame, background, and copy next?
