Best sizes for WordPress
Content images (blog posts, pages)
Keep images between 1200–1600 px wide and under 200 KB. This size loads fast, looks sharp on retina displays, and won't slow down your posts.
Hero images and featured images
For full-width banners or featured post images, use 1600–2000 px wide and target 500 KB or less. These images are larger but still load quickly with the right compression.
Thumbnails and gallery images
WordPress automatically creates thumbnails, but you can help by starting with images under 200 KB. Smaller source files mean faster thumbnail generation and better performance.
When to use 200 KB vs 500 KB
- 200 KB: Blog post images, product photos, in-line images, anything in your content area
- 500 KB: Hero sections, full-width banners, featured images, portfolio showcase images
- Rule of thumb: If it's smaller than 1600 px wide, target 200 KB. If it's full-width or a hero, 500 KB is fine
WebP (optional) vs JPEG
Modern WordPress supports WebP, which can be 20–30% smaller than JPEG. However, JPEG works everywhere and compresses beautifully. SnapPress keeps it simple with JPEG—fast, universal, and perfect for WordPress.
If your theme or plugin converts to WebP automatically, great! If not, JPEG at 200–500 KB is already optimized and loads fast.
