How-to Guide

Create Photo Collages Optimized for Pinterest

Pinterest is a visual search engine, and tall images win. A vertical photo collage at 2:3 ratio (1000px (format Pinterest 2:3)) takes up maximum feed real estate: more visibility, more saves, more clicks.

Try MergeFrame (Free)

Pinterest rewards vertical images: a tall 2:3 Pin takes up more feed space than a square Pin.

Most effective formats: (1) Step-by-step stack: 3–4 images vertically for DIY/recipes, (2) Collection showcase: 2×3 product grid, (3) Before/after vertical: 2 stacked images for transformation content, (4) Mood board: 2×3 showing colors, textures, inspiration.

Always include text overlay: Pinterest's visual AI reads image text for ranking. Add your Pin title in clear font at the top. Use bright, high-contrast photos: dark images underperform on Pinterest's light interface.

How to Do It: Step by Step
