Free 3D Model Stats & Polygon Counter
Drop any 3D file to instantly see polygon count, vertex count, mesh objects, materials, textures, bounding box, and file size — all in the browser.
What Gets Reported
A full geometry breakdown for every 3D file you drop.
Polygon & vertex counts
Total triangle faces and vertex positions across all meshes in the file.
Mesh & material counts
Number of separate mesh objects and unique materials — useful for draw call estimation.
Texture count
Detects all textures referenced by materials, including albedo, normal, roughness, metalness, emissive, and AO maps.
Bounding box
The axis-aligned bounding box (AABB) dimensions in X, Y, and Z in the model's native units.

Frequently Asked Questions
What is polygon count and why does it matter?
Polygon count (or poly count) is the number of triangular faces in a 3D model. Lower counts render faster on GPUs, making them essential for real-time applications like games (typically under 100K polygons per character) and mobile AR/VR (often under 10K).
What is the difference between vertices and faces?
Vertices are the individual points in 3D space. Faces (triangles) are the surfaces formed by connecting three vertices. A model typically has roughly 1.5× as many edges as faces (Euler's formula for closed meshes).
What bounding box units does the tool use?
The bounding box is reported in the model's native units, which depend on how the file was exported. GLB/GLTF files are typically in meters; OBJ and FBX files may use centimeters, inches, or arbitrary units depending on the authoring tool.
Which file formats are supported?
GLB, GLTF, OBJ, FBX, STL, PLY, and DAE (Collada). All processing runs locally in your browser.
Does my file get uploaded?
No. All analysis runs locally in your browser using Three.js and WebGL. Your files never leave your device.
