Map Tile Calculator
Convert a longitude, latitude and zoom level into XYZ map tile coordinates and the tile's bounds — in your browser.

X/Y follow the usual XYZ (slippy map) scheme used by most tile servers; the TMS row gives the flipped Y that some older tooling expects.
How it works
- Enter a longitude, latitude and zoom level.
- The tile's z/x/y path, its TMS Y value and its bounding box are computed instantly on your device.
- Use the path directly in an XYZ tile URL template.
Frequently asked questions
- What are XYZ map tiles?
- Web maps are served as a pyramid of 256-pixel square images. At zoom level z the world is split into 2^z by 2^z tiles, each addressed by an x and y index. Most tile URLs are templates like /{z}/{x}/{y}.png.
- What is the TMS Y value?
- TMS numbers rows from the bottom instead of the top, so its Y is flipped relative to the XYZ scheme. Both are given because tooling in this space is split between the two conventions.
- Why are the poles excluded?
- Web Mercator, the projection these tiles use, stretches infinitely towards the poles and is conventionally clipped at about 85.05 degrees. Coordinates beyond that have no tile.
- Is anything sent to a server?
- No. No tile is fetched and no coordinate leaves your browser — this only computes which tile would contain your point.
