TL;DR: Use 1080 × 1920px at 9:16. Keep all key elements inside the 1080 × 1390px safe zone. Size text at 28pt or above. Test on a real phone before you post.
Instagram Story Dimensions & Aspect Ratio
Get the canvas right first. Every design decision flows from it.
1080 × 1920 pixels is the optimal size
Instagram Stories display at 1080 × 1920 pixels. That's the native resolution for the fullscreen vertical mobile format. Start here and your design stays sharp.
9:16 aspect ratio fills the fullscreen mobile format
The 9:16 ratio matches the full height of a phone screen. Content designed in any other ratio gets letterboxed or cropped. Design for 9:16 from the start.
Upload at exact resolution to minimize compression
Instagram compresses images on upload. Per Meta's Ads Guide, uploading at the exact 1080 × 1920 target minimizes compression artifacts and keeps your design crisp.
Understanding the Safe Zone
Not every pixel on your canvas is guaranteed to show. Interface elements cover the edges.
Keep critical elements within the 1080 × 1390px safe area
The safe zone sits at the center of your canvas. 1080 × 1390 pixels. Logos, faces, and CTAs belong here. Anything outside risks being clipped by device bezels or Instagram's UI.
Text should stay 250px from top and bottom
The top 250px holds the profile badge and the close button. The bottom 250px holds the reply bar. Keep all text outside these zones so it stays readable.
Link stickers belong in the middle-lower section to avoid reply bar coverage
Place link stickers in the middle-lower section of the safe zone. Too close to the bottom and the reply bar covers them entirely.
Why safe zones matter. avoiding hidden content on different devices
Screen sizes vary across devices. A layout that looks complete on one phone crops on another. Staying inside the safe zone keeps your design consistent everywhere.
Text & Typography in Stories
Readable text drives action. Unreadable text gets skipped.
Minimum 28-36pt text size for readability
Text smaller than 28pt is hard to read on a phone screen. Aim for 28pt at minimum. For headlines, go 36pt or larger.
Use 1-2 fonts per story for consistency
More than two fonts creates visual noise. Pick one headline font and one body font. Stick to them across the slide.
Choose sans-serif fonts for mobile clarity
Sans-serif fonts render more cleanly at small sizes on mobile screens. They're the safer default for Story text.
Ensure high-contrast text on photo/video backgrounds
Light text on a dark background or dark text on a light one. Low-contrast text disappears on busy photo backgrounds. Add a semi-transparent color block behind text if contrast is borderline.
Using Instagram's Native Design Tools
Instagram's built-in editor covers most Story design needs without leaving the app. Per Instagram's Help Center, native tools include drawing, text, stickers, GIFs, filters, and effects.
The drawing and brush tools let you add freehand accents or emphasis marks. The text tool handles headlines, captions, and overlays in multiple fonts and colors. Stickers, GIFs, and emojis add interactivity and personality. Filters and color adjustments unify the visual tone across a series of slides. The Cutouts feature uses AI background removal to turn any photo into a custom sticker for your Story.
Design Best Practices for Stories
Good design principles don't change by format.
Choose high-contrast color pairs. Use one focal point per slide to keep the eye from getting lost. Test your finished design on a real phone before posting. Small text that reads fine on desktop can fail completely on mobile. Place your CTA where it draws the eye naturally, not where it barely fits.

Frequently Asked Questions
What size should an Instagram Story post be?
The optimal size for an Instagram Story post is 1080 × 1920 pixels at a 9:16 aspect ratio. This fills the fullscreen vertical format on mobile devices. Uploading at exactly this resolution also minimizes Instagram's compression.
What is the safe zone for Instagram Stories?
The safe zone for Instagram Stories is 1080 × 1390 pixels, centered on the canvas. Keep text at least 250 pixels from the top and bottom edges to avoid overlap with Instagram's UI elements like the profile badge and reply bar.
What font size should I use for Instagram Story text?
Use a minimum of 28pt for body text in Instagram Stories. For headlines, 36pt or larger is recommended. Anything smaller becomes difficult to read on a phone screen.
Can I resize a feed post to fit Instagram Stories?
Yes, but feed posts are typically square (1:1) or portrait (4:5), so they need to be resized to 9:16 for Stories. Tools like Coinis Revise with Smart Resize can adapt existing designs to 1080 × 1920 without manual cropping.
