CAROUSEL SIZE REFERENCE

Instagram carousel size: choose one canvas and keep the sequence consistent.

Use a portrait or square production system that preserves mobile readability from cover to final slide. Platform behavior changes, so preview current crop handling instead of assuming mixed artwork will always display the same way.

A CSS reference comparing consistent portrait and square slide systems.
QUICK ANSWER

Start with the job, then choose the frame.

A 1080 × 1350 pixel 4:5 portrait canvas uses more feed height, while 1080 × 1080 square is a flexible alternative. Use one consistent ratio for a predictable sequence and check current Instagram carousel behavior before publishing.

A consistent slide production grid

Use this reference to establish dimensions, margins, page markers, and export order before building the narrative.

01 / PRACTICAL GUIDANCE

Portrait or square: choose by content density

Portrait offers more vertical room for a headline and product view; square can be simpler to reuse. Pick the shape that supports the content, not just the one with the most pixels.

02 / PRACTICAL GUIDANCE

Keep shared margins truly shared

Define the same outer spacing, headline start, footer zone, and page marker across all slides. Consistency makes varied content easier to scan and reduces accidental jumps.

03 / PRACTICAL GUIDANCE

Export and name in sequence

Use zero-padded filenames or another stable ordering system, then review the full set as thumbnails. A strong individual card can still interrupt the story if it lands in the wrong position.

REPEATABLE WORKFLOW

Set up the carousel production file

Choose the canvas once, then control consistency and order.

  1. Select a 1080 × 1350 portrait or 1080 × 1080 square working canvas.
  2. Create shared content margins, type roles, and a page-number position.
  3. Build every slide inside the same system and inspect the sequence at phone size.
  4. Export with ordered filenames and confirm the current Instagram preview before posting.
COMMON QUESTIONS

Instagram carousel size FAQ

What size should an Instagram carousel be?

A consistent 1080 × 1350 portrait or 1080 × 1080 square workflow is practical. Confirm current Instagram behavior before publishing.

Can carousel slides use different ratios?

Platform support and crop behavior can evolve. For predictable design and review, use one ratio across the sequence unless you have tested the current mixed-format behavior.

Which ratio gives more feed space?

A 4:5 portrait image occupies more vertical feed area than a square image, but it also requires content designed specifically for that taller canvas.
