- 5 min read
A great photo can fall apart at export if the crop does not match the destination. This guide explains photo aspect ratio in plain language and shows how to work with the most common image aspect ratios in 2026: 3:2, 4:3, 1:1, and 16:9. You will learn when to pick each ratio in camera, how to crop for social (4:5, 9:16, 1:1), how to match popular print sizes (5:4, 3:2), and how to avoid losing important details at the edges.
Quick summary
Photo aspect ratio is the width-to-height of your image.
3:2 suits full-frame. 4:3 suits Micro Four Thirds and many phones. 1:1 is square. 16:9 is widescreen.
Choose your capture ratio based on final use: screen, social, or print.
Crop intentionally for social safe areas and print sizes to avoid trimming surprises.

What is photo aspect ratio
Photo aspect ratio describes the width to height of an image, written as W:H.
Examples: 3:2, 4:3, 1:1, 16:9, 4:5, 5:4, 9:16.
Why it matters:
It determines cropping for social or print.
It influences resolution use and how much you lose when you change ratios.
Aspect ratios 2026
Ratio | Where you’ll see it | Best for | Common web sizes* | Print matches | Social uses | Crop tips |
3:2 | Full-frame, APS-C | Landscapes, street, general shooting | 1200×800, 2400×1600, 3600×2400 | 4×6, 8×12, 12×18 | Post as landscape. Often cropped to 4:5 or 1:1 for feeds | Leave side room if you’ll crop to 4:5 or 1:1 later |
4:3 | Micro Four Thirds, many phones | Travel, documentary, mixed output | 1200×900, 2048×1536, 2400×1800 | 6×8, 9×12 | Easy crops to 1:1 and 4:5 | Watch edges. Compose a bit wider if planning 16:9 or 4:5 |
1:1 | Instagram grids, product pages | Minimal, centered compositions, product | 1080×1080, 1440×1440 | 8×8, 12×12 | Classic square posts | Keep subjects centered or using tight symmetry |
16:9 | Video, hero banners, YouTube thumbs | Wide scenes, web headers | 1280×720, 1920×1080, 2560×1440 | Rare in labs | Landscape posts, covers, thumbnails | Keep horizon on lower third. Vertical subjects feel cramped |
4:5 | Vertical social portraits | Portraits for mobile feeds | 1080×1350, 1200×1500 | Rare; 8×10 is 5:4, not 4:5 | Instagram vertical max height | Capture a bit wider in 3:2 so heads/hands aren’t cut |
5:4 | Classic print ratio | Framed prints, portraits | 1500×1200, 2000×1600 | 8×10, 16×20 | Posts fine, slightly wider than 4:5 | Protect sides if coming from 3:2. Compose for classic framing |
9:16 | Stories, Reels, Shorts | Full-screen vertical | 1080×1920, 1440×2560 | None | Stories, Reels, Shorts | Keep faces and text in center “safe” zone |
A-series (√2) | A5, A4, A3 prints | Documents, posters | A5/A4/A3 native | A5, A4, A3 | Not used | Doesn’t match 3:2 or 4:3 exactly. Expect slight trims |
* Web sizes are examples. Export to match your layout and device breakpoints.
Quick math for image aspect ratios
Aspect ratio = width ÷ height. Example: 6000×4000 px = 1.5 = 3:2.
Match prints: pick a paper size that equals your ratio to avoid trimming.
Change ratio loss: expect 5 to 20 percent loss on one dimension when converting across ratios.
The big four image aspect ratios
3:2
Where you see it: full-frame and APS-C cameras, many classic prints like 4×6 and 8×12.
Why use it: natural feel for landscapes, street, and general shooting.
Watch out for: cropping to 5:4 or 4:5 for prints or social will trim the sides.
4:3
Where you see it: Micro Four Thirds cameras, many smartphones.
Why use it: flexible for travel, documentary, and mixed output.
Watch out for: cropping to 16:9 or 1:1 removes more from edges.
1:1
Where you see it: Instagram grids, product and portrait minimalism.
Why use it: strong, simple compositions with clean balance.
Watch out for: requires planning. Compose central subjects to avoid awkward trims.
16:9
Where you see it: video, YouTube thumbnails, hero banners, presentations.
Why use it: wide, cinematic feel that fits screens perfectly.
Watch out for: vertical subjects can feel cramped. Consider 4:5 or 9:16 for mobile-first delivery.
Other useful ratios
4:5
Best for: tall social portraits (popular vertical crop).
Typical size: 1080×1350 for feeds.
Tip: capture a little wider when shooting 3:2 if you plan to crop 4:5.
5:4
Best for: classic prints like 8×10 and 16×20.
Tip: if you shoot 3:2, recompose with extra side space to protect key edges.
9:16
Best for: stories, reels, shorts, vertical slides.
Typical size: 1080×1920.
Tip: keep faces and text in the central safe zone.
How to choose the right aspect ratio
Match the final output – If printing 8×10, compose with 5:4 in mind. If going vertical social, plan for 4:5 or 9:16.
Consider subject orientation – Tall subjects benefit from 4:5 or 9:16. Wide vistas shine in 3:2 or 16:9.
Protect the edges – Put critical details away from borders when you know you’ll crop later.
Shoot a little wider – Extra margin gives you room to crop for social and print without losing essentials.
Social crop guide and safe areas
Feed
Square 1:1: 1080×1080. Safe pick for grids and sets.
Vertical 4:5:1080×1350. Maximum on many feeds. Keep faces and text centered.
Landscape 1.91:1: 1200×628 to 1350×708 works well for link previews and banners.
Stories, Reels, Shorts
9:16: 1080×1920. Place titles and logos in the central 80 percent. Avoid top and bottom UI zones.
YouTube
Thumbnail 16:9:1280×720. Design for clarity at tiny sizes. Use large, high-contrast subjects and readable type.
Tip: Export separate crops for each placement if the image is critical for a campaign.
Crop guide: from capture to export
1) Plan
Decide the target: social feed, story, print, or web banner.
Choose the closest capture ratio to reduce later trimming.
2) Compose
Protect edges. Avoid placing hands, elbows, or horizon lines right on the border.
Keep faces near the upper third for portraits.
Leave headroom if you need copy or UI overlays.
3) Edit
Crop to the target ratio early so you edit with the final frame in mind.
Straighten first, then crop.
Use overlays like thirds or golden ratio to refine balance.
4) Export
Create separate exports for each placement: 1:1, 4:5, 16:9, or 9:16.
Sharpen for output size.
Name files with the ratio in the filename, for example portrait-4x5-1080x1350.jpg.
FAQs
What is the best ratio for portraits?
4:5 for social feeds, 5:4 or 3:2 for prints. Choose based on delivery.
Is 3:2 or 4:3 better for general shooting?
Both work. 3:2 feels wide and classic. 4:3 is flexible and matches many phones.
Do I need separate exports for each platform?
Yes for critical images. Create 1:1, 4:5, and 16:9 or 9:16 versions to control composition and sharpness.
What ratio should I set in-camera?
Use the native ratio of your sensor to capture maximum pixels, then crop intentionally in post for final use.
How do I avoid cutting off important details when cropping?
Compose with extra space, keep key elements away from edges, and test your target crop overlay during editing.
