Composing for social media formats - frame with the platform in mind
You composed a beautiful photo - but when you post it, something feels wrong. The crop is tight. The subject’s off-centre. Or worse - your best detail is gone.
Welcome to the challenge of social media formats.
Every platform has its own preferred image shape - and that affects how your composition is framed, read, and remembered. Whether you're posting on Instagram, Facebook, or Stories, understanding how your photo will be displayed helps you compose and edit with intention.
Why social media crop matters
Subject placement shifts when your image is auto-cropped
Vertical formats dominate mobile viewing - taller images often perform better
Composition balance can break if cropped without planning
Important edges or negative space may be lost
You don’t need to shoot differently for every platform - but knowing the crop helps you compose with flexibility.
Tips for composing for multiple formats
Leave breathing room
Avoid tight edges - especially at the top and bottom. Give yourself space to crop later.Shoot slightly wider than needed
This gives you more options when cropping to square or vertical formats.Place key elements centrally
Especially for Stories and Reels where text overlays and UI may cover edges.Use leading lines that still work in vertical
Think foreground-to-background flow - not just side-to-side.Test-crop in editing apps
Before posting, try previewing different crops (Snapseed, Lightroom, Canva, etc.) to see how your composition holds up.
How to adapt composition after capture
Reframe with cropping tools
Use Lightroom or Snapseed to change aspect ratio intentionally.Use content-aware fill (or AI fill)
If cropping cuts off a key part, try extending the edges with generative tools - or the Expand tool inside Snapseed.Recompose with overlays
Use grid overlays to check new balance after cropping.
When to shoot specifically for a format
If you're creating a carousel or reel series with consistent framing
If your platform prioritizes one format (e.g. Instagram Stories or TikTok)
For commercial or branded content where layout matters
When layout and design (e.g. web banners or thumbnails) require exact dimensions
Did you know?
Instagram’s original square-only format shaped how a generation of photographers composed images. Many creators learned to center subjects more often, leave extra space, and prioritize simplicity. Today, with vertical formats dominating mobile feeds, the new rule is: go tall or get cropped.
Tips by format
1:1 (square): Great for centered subjects, symmetry, minimalism
4:5 (portrait): Ideal for portraits and vertical storytelling - takes up more screen space
9:16 (Stories/Reels): Compose in vertical thirds, avoid placing text or faces near the top
16:9 (wide): Use for landscapes or cinematic scenes - good for YouTube or presentations
21:9 (ultrawide): Shoot with panorama or crop intentionally for banners or headers
Common mistakes
Tight framing that loses key parts when cropped
Forgetting how image will be overlaid (e.g. text, icons, swipe arrows)
Over-reliance on centered framing for every format
Ignoring how vertical flow affects scroll-stopping power
Compose for how the photo will be seen - not just how it was shot.
