Designing Avatar Systems with Circular Images (Practical Playbooks)

August 30, 2025

Instead of abstract specs, here are playbooks for common products—what to prepare, how to crop, and what to export so avatars look great everywhere.


Playbook A — Team directory / About page

What users see: A grid/list of people at medium sizes (48–128 px).
Prepare: One sharp photo per person; prefer soft, uncluttered backgrounds.
Crop recipe in the tool:

  1. Center the face; set eye line slightly above center.
  2. Zoom until the forehead-to-chin fits with ~8% padding.
  3. Keep the same visual scale across the whole set by eyeballing against a reference. Export: Transparent PNG at a consistent size (e.g., 512 px).
    QA checklist: Scroll the finished page—do heads jump in size? Re-crop outliers to match.

Playbook B — Chat and messaging UI

What users see: Tiny circles (24–40 px) next to messages.
Prepare: Photos with strong contrast; avoid wide shots.
Crop recipe:

  1. Add a touch more space than you think—tight crops die at 24 px.
  2. Keep hair/ears inside the frame; watch for clipping at the top.
  3. If your UI shows presence rings, leave 2–4 px margin around the circle. Export: Transparent PNG. Provide @2x assets (e.g., 48 px slot → 96 px file).
    QA: On a low-end monitor, can you identify people instantly? If not, re-crop simpler and closer.

Playbook C — Product reviews / testimonials

What users see: Small to medium circles next to quotes.
Prepare: Ask for neutral, high-key photos; avoid heavy filters.
Crop recipe: Center the face; keep 10% padding for a relaxed feel.
Export: Transparent PNG; match the rest of your site’s corner radii and shadows (UI layer, not baked into the image).
QA: Do avatars align vertically with text baselines? If not, adjust CSS line-height—not the crop.


Playbook D — Marketplaces (sellers/creators)

What users see: Profile avatars overlaid on busy cards with price/tags.
Prepare: Choose images with a clear silhouette and simple colors.
Crop recipe: Leave extra outer space so badges/verification ticks don’t cover faces.
Export: Transparent PNG; keep background simple to avoid card clutter.
QA: Place a status ring/badge in the UI—does it overlap important features? Re-crop with more margin if needed.


Playbook E — Logos & app icons in navigation

What users see: Circles on headers/sidebars of varying colors.
Prepare: A simplified mark (monogram/bug) if your logo is very wide.
Crop recipe: Keep 8–12% padding from the rim; ensure strokes don’t kiss the edge.
Export: Transparent PNG. Test on light and dark themes.
QA: At 24–32 px, are strokes still crisp? If not, use a simplified mark.


Delivery & maintenance (what helps long-term)

  • Export a single large master (e.g., 1024 px) and generate smaller sizes in your build/UI.
  • Use predictable filenames (e.g., [email protected]) to help caching/CDN.
  • Provide a fallback silhouette for missing avatars.
  • Keep originals—re-crop later if your design changes.

Accessibility that actually helps users

  • For people, use alt text = person’s name (e.g., “Jamal Rivera”).
  • For decorative avatars (purely visual), set alt="" so screen readers skip them.
  • Avoid baking text into the image; provide labels in real text next to the avatar.

Privacy: All cropping runs locally in your browser; nothing is uploaded.
