Skool image sizes — the practical reference

The Skool image-sizes cheat sheet

Quick reference (mostly stable across 2024-26):

• Community banner: 1584×396 (4:1 aspect ratio, ~16:4)
• Community profile photo: 400×400 minimum, square — appears as the round community icon
• Owner / member profile photo: 400×400 minimum, square — round avatar
• Course thumbnail: 1280×720 (16:9) — appears as the lesson card
• Course banner inside Classroom: 1920×1080 recommended
• Post images: any size up to 10MB per image, multiple per post supported
• Calendar event cover: 1280×720 (16:9)
• DM attachments: up to 10MB per file

File types: JPG for photographs (smaller files, good compression), PNG for graphics with transparency or text-heavy images, GIF for animations (large files, use sparingly), WebP is supported but JPG / PNG are safer for compatibility.

Community banner — 1584×396

The community banner is the wide image at the top of your community page. It's the first impression for new members.

Dimensions: 1584×396 pixels, 4:1 aspect ratio. Skool crops anything else to this aspect — vertical photos look terrible, faces get cut off, branding gets clipped.

What works:

• Wide landscape photos with the focal point centred (Skool sometimes shows mobile crops differently)
• Branded graphics with your community's name and tagline in the centre
• Avoid placing important text in the bottom 20% — overlay UI sometimes covers it on mobile

File size: keep under 2MB for fast loading. JPG at quality 85 is the sweet spot for photographs. PNG for branded graphics.

If your banner looks blurry, upload at 2× resolution (3168×792) — Skool handles retina-display rendering and the larger source ensures sharpness on high-DPI screens.

Profile photo — 400×400 minimum, square

Both your personal profile photo and your community's profile photo are square images displayed in round avatars. Skool crops to a circle — anything in the corners gets cut.

Dimensions: 400×400 minimum, 1000×1000 ideal for retina sharpness. Larger is fine; Skool auto-resizes.

What works:

• Faces centred for personal profiles (head and shoulders, slightly cropped)
• Logos / icons centred in the frame for community profiles
• High contrast against the avatar background colour Skool uses

What doesn't:

• Wide group shots — your face gets lost
• Logos with text near the corners (clipped by the circular crop)
• Low-res images upscaled — looks blurry on retina displays

Course thumbnails — 1280×720 (16:9)

Each lesson and module in the Classroom has a thumbnail card. These render as 16:9 rectangles in the lesson list.

Dimensions: 1280×720, 16:9 aspect ratio. 1920×1080 is also fine and ensures sharpness on retina screens.

What works:

• Clean text overlay with the lesson title (helps members navigate)
• Consistent visual style across all lessons in a course (cohesion matters)
• High contrast for readability
• Brand colours that match your community banner

Most successful Skool course thumbnails follow YouTube-style conventions — bold text, consistent branding, easy-to-scan visuals. If you have a graphic designer, lock down a single thumbnail template and reuse it for every lesson.

Post images — flexible, up to 10MB

Images attached to community posts have no fixed aspect ratio. They render at their native size up to the post container's max width (~720px on desktop, full-width on mobile).

Dimensions: any size, up to 10MB per image. Multiple images per post supported.

What works:

• 1200×675 (16:9) for landscape content
• 1080×1080 (1:1) for Instagram-style square posts
• 1080×1350 (4:5) for portrait-leaning content (looks slightly cropped on desktop, full on mobile)
• 1500-pixel-wide minimum for retina sharpness

What doesn't:

• Tiny screenshots (under 600px wide) — they look pixelated when stretched
• Massive 50MB raw photos — Skool may reject or your upload will fail
• Images with critical text near edges — mobile cropping varies
