Zoom and intersecting tile counts
XYZ Web Mercator tiles covering nonwrapping bbox; boundary edges half-open.
Total estimated tile bytes
Total intersecting tile count × supplied mean bytes.

Assumptions & limits
Assumptions & limits
- Extent, zoom levels, tiling scheme. Returns Tile counts and estimated storage. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Web Mercator geographic bbox [west,south,east,north]: minimum None, maximum 1000000000000.0. Minimum zoom: minimum 0, maximum 20. Maximum zoom: minimum 0, maximum 20. Mean compressed bytes per tile: minimum 1e-12, maximum 1000000000000.0.
