Instagram Sizes
Instagram Post Size

The Instagram carousel size is 1080 × 1350 px (4:5 portrait) or 1080 × 1080 px (1:1 square), and every slide must use the same aspect ratio. Carousels hold up to 20 images or videos — here are the optimal dimensions, presets, and slide-count specs for 2026.
Instagram Reel Size
1080x1920 (9:16)
Instagram Reels are full-screen vertical videos that need precise dimensions to look sharp. The wrong size leads to cropping, black bars, or blurry playback. Here are the complete Instagram Reel specs for 2026.

LinkedIn Carousel Size

Cross-Platform Tips
9:16 is universal for vertical
1080x1920 (9:16) works for Instagram Stories, Reels, TikTok videos, TikTok slideshows, YouTube Shorts, and Facebook Stories. Design once, publish everywhere.
Always export at target resolution
Every platform re-compresses uploads. Starting at the exact recommended pixel dimensions avoids quality loss from resizing. Never upload below the minimum resolution.
PNG for text, JPG for photos
Use PNG when your image contains text, logos, or sharp lines — it preserves edges. Use JPG at 85-95% quality for photographs. This applies across all platforms.
