Instagram Content Sizes You Should Know
If you want your posts to look great on Instagram, knowing the right sizes is half the battle. Here’s a quick rundown of what works best in 2026.
Square Posts & Old Grid Content
Remember the classic Instagram grid? That clean, square look is still around, and some users still see it that way. If you want that timeless vibe, stick with 1080 × 1080 px. It’s simple, safe, and works for anyone who loves the original Instagram feel.
Current Feed Post Size (Recommended)
If you want your posts to look their best on most feeds in 2026, go for 1080 × 1350 px. This taller format gives you more room to show off your photos and keeps everything looking sharp. Just a heads-up: you might see a slightly different ratio (1013 × 1350 px) in your profile grid preview, but that’s just for display—Instagram won’t let you upload in that size. Stick with 1080 × 1350 for the best results.
Stories, Reels, and Instagram Lives
Want your Stories and Reels to fill the screen? Use 1080 × 1920 px. This vertical format is perfect for grabbing attention and making your content pop. Whether you’re sharing a quick update or a full Reel, this size keeps your visuals front and center.
All About Instagram Reels Sizes
Reels are taking over Instagram, and getting the size right is key to making your videos stand out. Here’s what you need to know for 2026.
Standard Reels Dimensions
Reels are all about movement and impact, so getting the size right matters. For most Reels, 1080 × 1920 px is the gold standard. It’s crisp, clear, and looks great on any device. If you want your Reel to fit the feed preview, 1013 × 1350 px is the way to go. But remember, this is just for how it looks in your grid—upload in 1080 × 1920 for the best quality.
Bonus: The New “Skinny” Cinematic Reels Format
Want to try something fresh and cinematic? The new 5120 × 1080 px format is making waves in 2026. It’s perfect for AI-generated videos, panoramic shots, and creative storytelling that stands out from the crowd.
