Aspect Ratios to Use for Blog Post Images
Aspect ratio is the shape of the image, and the wrong one leads to awkward crops. Articles often carry several images, and each extra megabyte delays the moment a reader can start scrolling.
Recommended settings for blog post images
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1200 px on the long edge |
| Quality | 70 |
| File size | 150 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
Aspect Ratios to Use
Common ratios are 1:1 square, 4:5 portrait, 3:2 classic photo and 16:9 widescreen. Pick the one that matches where the image will be displayed for blog post images.
Crop to the ratio first, then resize to about 1200 pixels on the long edge and compress. Cropping last can undo your careful sizing.
