How each image is scored
The checker downloads each image and reads its true dimensions, then sorts it into one of three groups.
| Verdict | What it means |
|---|---|
| Ideal | At least 600 pixels wide and close to a 2:3 shape, such as 1000 x 1500 |
| Pinnable | At least 600 pixels wide and vertical or square, but not close to 2:3 |
| Weak | Under 600 pixels wide, wider than it is tall, or taller than 1:2 |
What makes an image pin-ready
Shape comes first
Pinterest shows pins in vertical columns, so a 2:3 image takes up far more of the screen than a landscape one of the same width.
Width sets the ceiling
Below about 600 pixels wide, images look soft on high-resolution screens. 1000 x 1500 is the standard pin size and the one this checker scores against.
Alt text can become the description
When a reader saves your image with the browser button, Pinterest can start the pin description from its alt text. Empty alt text often means a pin with no keywords.
One tag can block everything
A <meta name="pinterest" content="nopin"> tag disables saving for the whole page. Some themes and plugins add it without telling you.
How to check whether your images are ready to pin
-
Step 1
Paste a URL
Enter the address of any public blog post, product page or listing on your site.
-
Step 2
Review each image
The checker downloads up to 12 images from the page and reports each one's real width, height and aspect ratio, with a verdict of ideal, pinnable or weak.
-
Step 3
Fix the weak ones
Add a vertical 2:3 image at least 600 pixels wide, write descriptive alt text, and remove any nopin meta tag that is blocking saves.
-
Step 4
Check again
Run the URL again to confirm the page now has at least one pin-ready image before you promote it.
Frequently asked questions
What image size does Pinterest want?
Pinterest recommends a 2:3 aspect ratio, with 1000 x 1500 pixels as the standard pin size. This checker marks an image as weak if it is under 600 pixels wide, wider than it is tall, or taller than 1:2, and as ideal when its shape is close to 2:3.
Why can nobody pin images from my blog?
The three usual causes are a nopin meta tag that blocks saves across the site, images that are too small, or a theme that only outputs one landscape featured image. This checker fetches your page and tests for all three, so you can see which one applies instead of guessing.
Does image alt text matter for Pinterest?
Yes. When someone saves an image from your site with the Pinterest browser button, Pinterest can use the image's alt text as the starting pin description. An image without alt text often arrives as a pin with no description, so it carries no keywords for Pinterest search.
What does the nopin tag do?
A meta tag with name "pinterest" and content "nopin" in a page's head tells Pinterest not to allow saves from that page, and a nopin attribute on a single image blocks only that image. Some themes and plugins add the tag without saying so. The checker reports when it finds the page-level tag.
How is this different from the Rich Pins Validator?
The Rich Pins Validator checks the metadata Pinterest reads from your page, such as title, description and price. This checker measures the images themselves: their true pixel dimensions and shape. Most sites need both, correct markup and at least one vertical image worth saving.
How many pages can I check?
You can check 10 pages every 24 hours, and no account is needed. Each check looks at up to 12 images on the page, including the og:image share image, and cannot measure image files larger than 2 MB, which it lists as unknown.
