3:4 is an aspect ratio — these are the pixel sizes people most often export after cropping. See the full 3:4 pixel dimensions table.
| Use | Pixels (W × H) |
|---|---|
| Product photo | 1200 × 1600 |
| Mobile portrait | 1080 × 1440 |
3:4 is a popular e-commerce product ratio — taller than square, it shows clothing and full products without wasted space.
Many phone cameras shoot 3:4 in portrait mode, so this crop usually needs only minor re-framing.
Keep the product or subject centered with even margins; 3:4 grids look cleanest when subjects are consistent.
Export at a consistent size across a product set (e.g. 1200×1600 px) so your gallery grid stays uniform.

3:4 is a portrait ratio common in mobile photography and e-commerce. It is taller than a square, making it ideal for product photos, full-body portraits, and vertical thumbnails. A typical size is 1200×1600 px.
Open the omnikitbolt crop tool, choose the 3:4 ratio, frame your subject vertically, and export. For product galleries, pick one export size (like 1200×1600 px) and apply it to every image for a uniform grid.
Both are portrait. 3:4 is slightly taller and is common on marketplaces and mobile. 4:5 is the Instagram feed limit. Choose 3:4 for store listings and 4:5 when posting the same product to Instagram.
No. Cropping discards only the pixels outside the 3:4 frame; the remaining image keeps full quality. Ensure the cropped area is large enough for your needs — around 1200×1600 px works for most product galleries.
