A technical decision page for people choosing dimensions, aspect ratio, file type, color mode, crop and padding for a specific Pinterest publishing route.
The correct Pinterest image size depends on where the image will be used. A standard image ad, an organic Image Pin, a catalog main product image, a Shopping Ad and a Collections secondary creative do not all share one universal rule.
Pixels and aspect ratio are different decisions
Aspect ratio describes shape. Pixels describe resolution. A 2:3 canvas can be 1000 × 1500, 1200 × 1800, or another proportional size. The image still fails if the product is tiny, the text is unreadable, or the file was upscaled from a weak source.
For standard image ads, Pinterest currently recommends a 2:3 aspect ratio or 1000 × 1500 pixels. For organic Image Pins, verify the current Image Pin spec because the file types and safe-zone guidance differ from ad specs. For retail catalogs, the main product image is tied to product-data requirements, not just a visual ad canvas.
Specification and format decision table
| Route or asset | Current spec to verify | Best export decision | Crop or padding choice | Risk if ignored |
|---|---|---|---|---|
| Standard image ad | PNG/JPEG, 20 MB desktop or 32 MB in-app, recommended 2:3 or 1000 × 1500. | Use a vertical JPG for photos or PNG for graphic/text-heavy creative in sRGB. | Design as 2:3; do not stretch a square product. | Tall ratios may be cut off; small text may fail on mobile. |
| Organic Image Pin | Current Image Pin file types include BMP, JPEG, PNG, TIFF and WEBP, with web and app limits. | Choose the format that preserves clarity before upload; preview the published Pin. | Use safe zones for text and important elements. | Visible text or important elements can land under UI or become unreadable. |
| Retail catalog main image | Main image_link requirements, product accuracy, URL accessibility and placeholder restrictions. | Use a clean product image that matches the exact item and variant. | Keep product prominent without deceptive crop or template overlay. | Catalog ingestion, distribution or shopper trust can fail. |
| Shopping Ad | Shopping Ads follow standard image/video specs and depend on Product Pins from catalogs. | Prepare the image as product-led creative, then validate product group and eligibility. | Use the ad-safe crop, but keep product-page consistency. | Image may look acceptable but the product may still be ineligible. |
| Collections secondary image | Collections specs: secondary creatives share the same aspect ratio, with 1:1 recommended for control. | Export consistent secondary images that support the hero creative. | Keep important detail centered if non-1:1 center cropping may occur. | Secondary products can crop unpredictably or look inconsistent. |
JPG versus PNG for Pinterest
Use JPG for photographic product, food, fashion, home decor and lifestyle imagery when transparency is not needed. Use PNG for text-heavy Pin designs, diagrams, screenshots, logos, icons and crisp graphic edges. PNG does not prevent every quality issue, because Pinterest still processes uploads, but it can preserve sharp source edges better before platform conversion.
Pinterest’s ad specs say uploaded images become standard 8-bit RGB JPEGs and recommend PNG with sRGB to reduce quality loss. If your image has a custom color profile, export a clean sRGB delivery copy and inspect the uploaded preview.
Crop, pad, resize or redesign?
- Crop when empty or unimportant edges can be removed safely.
- Pad when a product needs breathing room inside a vertical canvas.
- Resize when the shape is correct but the pixel dimensions are too large or small.
- Redesign when a square or landscape layout cannot become a readable vertical Pin without rebuilding hierarchy.
Do not choose one batch setting for every asset
A product photo, a text overlay Pin and a catalog image have different failure points. Before exporting a large set, sample one photo-led image, one text-heavy image and one product-only image. Check sharpness, color, crop, file size and destination match before processing the rest.
FAQs about Pinterest image specs and formats
No. It is the common recommended size for standard image ads because it is a 2:3 canvas. Organic Image Pins, Collections, carousel and catalog images have their own requirements to verify.
Crop only if no important detail is lost. Pad when the product needs space. Redesign when the square layout becomes awkward or unreadable in a vertical canvas.
PNG can be better for graphics, logos, screenshots and text-heavy designs. JPG is usually practical for photos. The best choice depends on the asset and the Pinterest route.
Yes, sRGB is the safer web-display choice. Pinterest says custom color profiles are unsupported and may cause slightly different colors on published Pins and ads.
Compress only until the delivery copy stays clear at mobile preview size. Watch for fuzzy text, halos, banding, blocked gradients and damaged product texture instead of relying on one universal percentage.
Not exactly. Shopping Ads follow standard image or video ad specs, but Product Pin images also depend on catalog fields, product accuracy, accessible image URLs and merchant/product eligibility.
