Pinterest is built around tall images. Its recommended ratio is 2:3, such as 1000 × 1500 pixels, and very tall images get cut off in the feed. Images exported from other platforms, cameras or design templates are often a little off, which can mean a cropped title or a pin that looks smaller than the ones around it. This checker reads the exact pixel size of every image you add and tells you how each one will fit.
For any image that is not 2:3, the Fix button creates a 1000 × 1500 version: fitted over a blurred copy of the photo, fitted on a solid color, or cropped from the center. You can fix a whole batch and download it as a ZIP. Nothing is uploaded.
Pinterest aspect ratios explained
Aspect ratio is width compared with height. A 2:3 image is one and a half times as tall as it is wide, so 1000 × 1500, 600 × 900 and 2000 × 3000 are all 2:3. Pinterest recommends 2:3 for standard pins because it fills a feed column nicely without dominating it. 9:16 (1080 × 1920) is common for long pins and video covers.
Pinterest cuts off images taller than 1:2.1 in the feed, so anything taller than 1000 × 2100 loses its bottom part until someone opens it. Square and landscape images are allowed but take up less room, which makes them easier to scroll past. See the full pin size guide for every format.
Crop or pad?
Cropping keeps the image full bleed but removes the top and bottom or the sides, so check that nothing important is near the edges. Fitting keeps the whole image and fills the gaps, which is safer for infographics, screenshots and anything with text. The blurred background option usually looks more natural than a flat color.
For more control over the crop, use the pin image resizer. If your images are also large files, run them through the image compressor.
