Instagram Aspect Ratio Calculator
Calculate image aspect ratios, decimals, DPI print dimensions, and UI safe zone overlays across Instagram, TikTok, LinkedIn, and Pinterest. Built for creators, social media managers, and digital marketing agencies.
Standard Social Media Aspect Ratios
Social platforms recommend specific aspect ratios for maximum screen coverage and engagement:
- Instagram Feed Portrait (4:5): 1080 × 1350 px — occupies the most vertical space in the mobile feed.
- Reels & TikTok Vertical (9:16): 1080 × 1920 px — full-screen immersive vertical video.
- Square Post (1:1): 1080 × 1080 px — classic universal social format.
- LinkedIn / Landscape (1.91:1): 1200 × 627 px — optimal for link preview cards and corporate feed banners.
- Pinterest Standard Pin (2:3): 1000 × 1500 px — vertical pin format favored by Pinterest discovery algorithms.
Why Safe Zones Matter for Mobile Creators
When uploading vertical video (9:16) or tall portrait posts (4:5), native mobile interfaces overlay icons, comments, and captions directly over your content. Keeping essential headlines, logos, and call-to-action text inside the designated safe zone ensures your message is never blocked by app buttons or user handles.
