# Polygon Count

Polygon count (poly count) is the number of polygons in a 3D model, directly affecting rendering performance and visual detail.

## What is Polygon Count?

**Polygon count** (or "poly count") is the total number of polygons, usually measured in triangles, that make up a 3D [mesh](/glossary/mesh). It's one of the key contributors to a model's rendering cost and file size: more polygons means more work for the GPU, though draw calls, texture size, shader complexity, and overdraw often matter just as much.

## Triangles vs Polygons vs Vertices

These metrics are often confused:

- **Vertices (verts)**: corner points
- **Polygons (polys)**: faces (usually quads while modeling)
- **Triangles (tris)**: what the GPU actually renders (1 quad = 2 tris)

Game engines report **triangle count**, since that's the real rendering cost. A "10k poly" character might be "20k tris."

## Recommended Poly Counts

| Asset | Triangle Budget |
|-------|-----------------|
| Mobile prop | 300 to 1,500 |
| Mobile character | 3,000 to 10,000 |
| PC/console prop | 1,000 to 10,000 |
| PC/console character | 20,000 to 80,000 |
| VR asset | Keep low (rendered twice, per eye) |
| 3D print | Count doesn't matter (no real-time) |

## Managing Poly Count

- **[LOD](/glossary/lod)**: swap to lower-poly versions at distance
- **[Normal maps](/glossary/normal-map)**: fake detail without geometry
- **[Retopology](/glossary/retopology)**: rebuild dense sculpts efficiently
- **Decimation**: algorithmic reduction (last resort)

## Polygon Count in Sloyd

Sloyd lets you control model quality, which directly affects polygon count. Lower quality = fewer polygons for mobile/web; higher quality = more detail for hero assets. Every model targets efficient, game-ready poly counts.

## FAQ

### What is a good polygon count for a game model?

It depends on the platform and the asset's role. Mobile props sit around 300 to 1,500 triangles and mobile characters 3,000 to 10,000, while PC and console characters can run 20,000 to 80,000. VR assets are kept lean because they render twice, once per eye.

### What is the difference between polygons, triangles, and vertices?

Vertices are the corner points, polygons are the faces between them (often quads while modeling), and triangles are what the GPU actually renders, where one quad equals two triangles. Game engines report triangle count because that is the true rendering cost, so a 10k-poly character may be 20k triangles.

### How do I reduce a model's polygon count?

Use level of detail to swap in simpler meshes at distance, bake fine detail into a normal map instead of geometry, retopologize dense sculpts into efficient meshes, and decimate as a last resort. Sloyd lets you set model quality so poly count is right-sized from the start.

### Does polygon count affect performance?

Yes, but it is only one factor. More triangles mean more work for the GPU per frame and a larger file, yet draw calls, texture size, shader complexity, and overdraw often matter just as much. A well-optimized scene balances polygon budget against all of these.

### Does polygon count matter for 3D printing?

Far less than for real-time. A printer only cares that the mesh is watertight and detailed enough for its resolution, so there is no frame-rate budget to hit. Extremely dense prints can produce huge STL files that slow the slicer, but visual polygon budgets do not apply.

### What is a high-poly versus a low-poly model?

High-poly models carry millions of polygons for maximum detail and are used for sculpting, film, and baking. Low-poly models use a deliberately small budget for real-time performance, and detail from the high-poly version is often baked onto them as a normal map.

### How do I check the polygon count of a model?

Every 3D tool shows it in a statistics or scene panel: Blender's overlay, Maya's heads-up display, or the import stats in Unity and Unreal. When you compare figures, confirm whether the number is triangles or quads, because that changes the total by up to a factor of two.
