Image Size & Dimensions Checker

Check the width, height, aspect ratio, megapixels and file size of images.

How do I check the dimensions of an image?

An image size checker reads a picture file and reports its pixel dimensions (width × height), aspect ratio, resolution in megapixels and file size.

What you get for each image

Width and height in pixels
Aspect ratio (e.g. 16:9, 3:2, 1:1)
Megapixels
File size and type
Orientation: landscape, portrait or square

Phone photos are measured the way they are displayed (with their rotation applied). Check many images at once to make sure they meet the requirements of a marketplace, CMS or social network before uploading.

Need a different size? Use the Image Resizer, or work out proportions with the Aspect Ratio Calculator.

Frequently asked questions

What is the difference between dimensions and file size?

Dimensions are the number of pixels (e.g. 1920 × 1080); file size is how many bytes the file takes, which depends on format and compression.

Does it show DPI?

DPI only matters for printing and is not shown; for screens, pixel dimensions are what count.

Are my images uploaded?

No, they are read in your browser.
