Convert an image to 2:3 ratio
2:3 is a tall portrait ratio and the exact proportion of one of the most common poster print sizes: 24×36 inches. It is also the most-cited recommended ratio for Pinterest pins, and a frequent choice for traditional paperback book covers.

How to convert your image to 2:3 ratio
Upload your image using the tool above.
A portrait-oriented photo with the main subject centered crops cleanly to 2:3.
For wide landscape photos, pad mode keeps the full scene inside the tall poster frame, though it will add empty space on the sides.
For print output, download as PNG at maximum resolution and set your print DPI in the design software before sending to the printer.
Why do you need to convert to 2:3 ratio?
The 24×36 inch poster — the format hanging in dorm rooms, cinemas, and offices worldwide — is exactly 2:3. Pinterest also recommends 2:3 as the optimal pin ratio because it shows more of the image in the feed without being cut off. If your goal is either of these use cases, converting to 2:3 before exporting means the printer or platform receives exactly the frame you designed.
Common pixel sizes for this ratio (2:3)
Where this ratio is used
- Poster prints at the standard 24×36 inch size
- Pinterest pins (Pinterest's most frequently recommended ratio)
- Paperback book covers
- Movie-style portrait posters and flyers
Crop or pad — which should you use for this ratio?
A tall subject — a standing figure, a building — roughly centered in the frame crops well to 2:3. Wide landscape photos are a different story: padding keeps the entire scene visible inside the tall poster frame, at the cost of some empty space along the sides.
How this ratio compares to a similar one
2:3 vs 3:4: 2:3 stretches noticeably further from top to bottom, matching classic 24×36 inch posters and Pinterest's top recommendation; 3:4 stays more compact and closer to a standard tablet screen's proportions. For print posters specifically, 2:3 remains the more standard choice.
Frequently asked questions
Is 2:3 better than 4:5 for Pinterest pins?
Pinterest officially recommends 2:3 as the optimal ratio (1000×1500 px), since it shows more fully in the feed without being cut off. 4:5 also works but displays slightly more compressed in some layouts.
Why is 2:3 the standard for posters specifically?
24×36 inches simplifies to a 2:3 ratio, and this has been a standard commercial poster frame and printing size for decades, so most print labs and frame manufacturers default to it.
Will a wide landscape photo work well converted to 2:3?
Not usually — 2:3 is quite tall and narrow, so a wide landscape photo loses most of its width when cropped. This ratio works best with photos that already have some vertical subject matter (a person, a building, a tall object).
Why does Pinterest recommend 2:3 over other ratios?
Pinterest's feed is a vertical, scrolling grid, and 2:3 pins show more fully without being visually cut off compared to a square or wider image, which tends to get visually compressed in their layout.
What DPI should I use when printing a 2:3 poster?
For a poster viewed from a normal distance (a few feet away), 100-150 DPI is usually sufficient; close-viewing prints like book covers should use 300 DPI for crisp detail.
