How this service works
Metres per pixel, map scale (1:N) and tile width on the ground for a zoom level and latitude.
Output
Returns a JSON object containing metres per pixel, feet per pixel, scale denominator (1:N), tile width in metres, tiles across the world, world width in pixels, metres per pixel at the equator, plus the echo of input parameters (zoom, latitude, tile size, DPI) and optional metadata such as source, summary, disclaimer and degraded flag.
Example use cases
Pixel-to-real-world distance conversion
“For a web map at zoom level 14 and latitude 48.85, how many metres does each pixel represent and how wide is a tile on the ground?”
Map scale label for print cartography
“I need to print a map using zoom level 12 at latitude 40.7 — what's the map scale denominator so I can add a '1:N' scale label?”
Storage estimate planning for tile server
“Before I estimate tile storage, can you tell me the ground resolution and tiles-across-the-world count at zoom level 18 near the equator with 256px tiles?”
Technical details
Endpoint
GEThttps://map-tiles.x402tookit.com/ground-resolution?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need precise ground-resolution figures (metres/feet per pixel, map scale, tile footprint) for a specific zoom level and latitude on a Web Mercator slippy map. It is the right choice when building map scale bars, computing pixel-to-distance conversions, estimating tile storage sizes, or validating display accuracy at different latitudes. Prefer it over manual formula implementations when you want a ready-made, authoritative computation with optional DPI-adjusted scale denominators.
Side effects
- Missing required zoom parameter returns an error
- Zoom value outside 0–24 range may return an error or unexpected result
- Latitude outside ±85.0511 is invalid for Web Mercator and may be rejected
- Non-integer zoom value may fail schema validation
- Network or payment (x402) failure results in no response
