What Kind of Canvas Is Best for Posting on Instagram? 2025 Guide to Sizes, Ratios, and Export Settings

![hero]()

Quick answer

If you want a one-size-fits-most canvas for feed posts, pick 4:5 portrait at 1080 × 1350 pixels. It’s the tallest aspect ratio Instagram shows in the standard feed without cropping, which means it occupies more vertical real estate, is harder to scroll past, and typically earns more engagement than square or landscape posts.

Why 4:5 generally outperforms square and landscape:

• It fills more of the feed on most phones, attracting attention.
• It preserves detail better than 1:1 at the same width because it’s taller.
• It avoids the small, letterbox feel of landscape (≈1.91:1), which often looks tiny on mobile.

As of 2025, 4:5 remains the practical sweet spot for most creators and brands posting to the feed.

Master Canvas Strategy (Design at 2×, Deliver at 1080 Wide)

Designing at double resolution gives you headroom for fine adjustments, cleaner edges, and better downscaling. Create once at 2×, export at 1080-wide deliverables.

Suggested master canvases:

• Feed portrait: 2160 × 2700 (export to 1080 × 1350)
• Feed square: 2160 × 2160 (export to 1080 × 1080)
• Feed landscape: 2160 × 1200 (export to 1080 × 566; keep full 1.91:1, then crop to 566 high)
• Stories/Reels: 2160 × 3840 (export to 1080 × 1920)
• Reel covers: 2160 × 3840 with safe center guides (see below)

Benefits:

• Higher-fidelity source for typography and line art.
• Cleaner gradients after downscaling.
• More forgiving for minor retouching.

Safe-Area Guides (Don’t Let the UI Cover Your Message)

![diagram]()

Keep text, logos, and faces away from edges so they don’t get cropped or covered by UI elements.

• Feed (4:5, 1080 × 1350)
• Keep a 40–64 px buffer around all sides.
• If your subject is tight, give at least 80 px at top/bottom to handle minor app crops and different device framings.
• Stories/Reels (9:16, 1080 × 1920)
• Avoid UI overlays by leaving ~250 px clear at the top and bottom.
• Practical “safe core” area: 1080 × 1420 centered vertically.
• Keep captions, CTAs, and tags inside this safe core.
• Reel covers (uploaded 9:16, 1080 × 1920)
• Grid crop: center 1080 × 1080 will display in your profile grid.
• Feed preview: central 4:5 area (1080 × 1350) shows in the home feed.
• Place title/logo within the overlapping center so it reads in both contexts.
• Carousels
• First slide sets aspect ratio—prepare all slides identically.
• Use 40–64 px edge buffers across all slides.
• For seamless panoramas, design a master width equal to slides × 1080 (e.g., 10 slides: 10800 × 1350), then slice on 1080 px columns.

Pro tip: In Figma/Photoshop, create reusable guides and lock them into your templates so you never guess.

Format, Color, and Resolution Best Practices

• Format
• Photos: JPEG at quality ~80 (70–85 sweet spot).
• Graphics/text, flat colors, UI mockups: PNG for sharp edges and no JPEG artifacts.
• Avoid TIFF and HEIC uploads; Instagram will recompress anyway.
• Color
• Embed sRGB IEC61966-2.1. This is the safest common denominator across devices.
• Avoid CMYK and Display P3 unless you specifically test across devices; P3 can shift on non‑color‑managed viewers.
• 8‑bit color is sufficient; 16‑bit adds weight without visible benefit on-platform.
• Resolution
• DPI/PPI does not affect on-screen rendering. Use 72–144 PPI to keep metadata tidy (some apps bloat files with high PPI).
• Deliver at 1080 px width for feeds and 1080 × 1920 for Stories/Reels.

Compression and Sharpening (Crisp, Not Crunchy)

Instagram recompresses uploads. Help it by feeding clean, efficient files:

• Target file size: roughly 200 KB–1.5 MB per image.
• Downscale using “Bicubic Sharper” (Photoshop) or a high‑quality resizer.
• Apply subtle output sharpening after downscaling:
• For photos: a light unsharp mask or smart sharpen (e.g., radius 0.3–0.5, amount 30–60%).
• For graphics/text: minimal sharpening; focus on crisp vectors and clean edges.

Example workflows:

• Photoshop (Export As)

1. Convert to Profile: sRGB IEC61966-2.1.
2. Image Size: set longest edge to 1350 (feed 4:5) or 1920 (Stories/Reels).
3. Resample: Bicubic Sharper (reduction).
4. Format: JPEG quality ~80 or PNG for sharp graphics.
5. Check final size; adjust quality slightly to land in target range.

• Lightroom Classic (Export)

1. Resize to Fit: Long Edge 1350 px (feed) or 1920 px (Stories/Reels).
2. Output Sharpening: Low or Standard for Screen.
3. Color Space: sRGB.
4. File Settings: JPEG Quality 75–85.

• ImageMagick (CLI)

## Feed portrait: 2160×2700 master to 1080×1350 JPEG with light sharpening

Use-Case Recommendations

• Photographers, creators, lifestyle: 4:5 portrait to maximize screen presence and detail.
• Illustrators, designers:
• Square for grid harmony and modular series.
• 4:5 when pieces have vertical storytelling or fine detail.
• Brands and educators:
• 4:5 carousels for step-by-step explainers and infographics.
• Square when the grid preview carries equal importance for campaigns.
• Landscape only when it’s essential:
• Cinematic stills, true panoramas, screenshots of widescreen UIs, or when negative space is part of the art direction.

Carousels and Consistency

• Uniform ratio: Make all slides the same aspect ratio; the first slide locks it.
• Visual rhythm: Repeat gutters, heading styles, and anchor positions to guide viewers.
• Seamless panoramas:
• Master canvas for 10 slides at 4:5: 10800 × 1350.
• Place vertical guides every 1080 px.
• Design across the full width; keep text away from slice boundaries.
• Export and slice precisely on guides.

Example slice command (ImageMagick):

## Slice a 10800×1350 panorama into 10 tiles of 1080×1350

Common Pitfalls and How to Fix Them

• Text too close to edges
• Fix: Add 40–64 px feed buffer; 250 px top/bottom safe zones for Stories/Reels; use locked templates with guides.
• Mismatched ratios in a carousel
• Fix: Decide the ratio first; generate a multi-slide template; confirm the first slide’s ratio matches all exports.
• Dull or shifted colors after upload
• Fix: Embed sRGB IEC61966-2.1; avoid CMYK/P3 unless tested; disable “Preserve Adobe RGB/ProPhoto” on export.
• Overly large PNGs causing heavy recompression
• Fix: Prefer JPEG ~80 for photos; if using PNG for graphics, consider indexed PNG (where appropriate) or hybrid workflows (SVG rasterization at export).
• Upscaling low-res images
• Fix: Don’t upscale beyond capture resolution; instead, design within 1080-wide output and lean on composition and typography.
• Banding in gradients
• Fix: Add very light dithering/noise before export; keep to sRGB; avoid over-compression.
• Soft-looking uploads
• Fix: Downscale cleanly and apply subtle output sharpening after resizing.
• Ignoring Reel cover crops
• Fix: Design cover with a centered 1080 × 1080 safe square and a centered 1080 × 1350 area for feed previews.

Bottom Line

For most posts in 2025, the best Instagram canvas is a 4:5 portrait at 1080 × 1350. Design at 2× for flexibility, keep critical content inside safe areas, export in sRGB with sensible compression, and maintain consistent ratios across carousels. This workflow preserves detail, avoids nasty platform recompression surprises, and helps your content stand out in the feed.
