What size should an Instagram feed post be?

1080×1350 pixels (4:5 portrait) is the tallest ratio Instagram's feed shows without cropping, and the platform's own recommended size; 1080×1080 square also works without cropping.

Do Stories, Reels and Shorts use the same size?

Yes — all three use the same 1080×1920 (9:16) vertical frame, so one template covers Instagram Stories, Reels, TikTok and YouTube Shorts covers.

How do I build a LinkedIn carousel?

Design slides at 1080×1350 (portrait), 1080×1080 (square) or 1920×1080 (landscape for data), then use the LinkedIn carousel maker to combine them into the PDF document post LinkedIn requires.

What if my exported image is the wrong size?

Use the image resizer to crop any uploaded image to an exact platform preset in your browser — no design software needed.

Are these official platform specifications?

They reflect current widely-used guidance and the same figures used by SkedCast's own resize and carousel tools; platforms can and do change supported sizes, so treat them as current-best-practice rather than a permanent guarantee.

Key takeaways

Feed posts on Instagram and Facebook render best at 1080×1350 (4:5 portrait, the tallest ratio these feeds show without cropping) or 1080×1080 (square).
Stories, Reels and Shorts share the same 1080×1920 (9:16) vertical frame across Instagram, Facebook and TikTok.
A LinkedIn carousel is a document post — build slides at 1080×1350 portrait, 1080×1080 square, or 1920×1080 landscape for data-heavy slides.

Instagram post templates: feed post templates

Instagram feed post — 1080×1350 (portrait 4:5, most of the vertical space Instagram's feed allows) or 1080×1080 (square)
Facebook feed post — same two options, 1080×1350 portrait or 1080×1080 square
LinkedIn feed image — 1200×1200 square
X in-post image — 1200×675 (16:9 landscape)
Pinterest standard Pin — 1000×1500 (2:3 portrait)

Story, Reel and Short templates

Stories, Reels and Shorts all use the same tall 1080×1920 (9:16) vertical frame — a single template built at this size works as an Instagram Story, an Instagram/Facebook Reel cover, a TikTok cover, or a Pinterest Idea Pin (9:16) with no reformatting.

Carousel templates

A carousel is a set of same-size slides. Instagram/Facebook image carousels use the same feed-post sizes above (1080×1350 or 1080×1080) repeated per slide. LinkedIn carousels are uploaded as a PDF document post — build slides at 1080×1350 portrait, 1080×1080 square, or 1920×1080 landscape for slides with charts or tables; SkedCast's LinkedIn carousel maker turns a set of images into that PDF automatically.

Getting your own images to these sizes

Once your design tool exports at the wrong size, the image resizer above crops any uploaded image to an exact target size in the browser — pick the platform and format and it center-crops to fit, no design software required.
