Overview
The viewport statistics feature lets you check the polygon count, vertex count, and other information for selected objects or the entire scene.
How to Enable
Click the dropdown arrow next to the "Viewport Overlays" button in the upper right of the 3D viewport, then check "Statistics".

Information Displayed
When statistics are enabled, the following information appears in the upper left of the viewport:

- Objects: Selected/total object count
- Vertices: Selected/total vertex count
- Edges: Selected/total edge count
- Faces: Selected/total face count
- Triangles: Selected/total triangle polygon count
Additional Notes
This is useful for checking polygon counts before exporting to a game engine, or as a performance reference during modeling work.
