Why Map Measurer exists
Map Measurer is a free tool for measuring distance, radius, area and elevation on a map — no account, no download, no watermark. This page explains who builds it and the principles behind it.
The problem we set out to solve
Most people who need to measure something on a map don't need a GIS package or a subscription — they have one specific question. How far is that running loop? How big is this garden? What area falls within a 20-minute cycle of the office? The existing answers tend to fall into two camps: heavyweight professional software that's overkill, or free tools buried under pop-ups, forced sign-ups and clutter.
We built Map Measurer to be the tool we wanted ourselves: open the page, click on the map, read the number. It does the three measurements people ask for most — distance along a route, a radius with its area and perimeter, and an elevation profile — and it does them on one map without making you choose a plan or create a login.
What we care about
- Genuinely free. Every feature is available to everyone. We cover the running costs with a couple of unobtrusive ads, never by gating measurements behind a paywall.
- Private by default. Your measurements happen in your browser. We don't ask you to register, and we don't store your routes or locations on a server. Read exactly how this works in our Privacy Policy.
- Honest about accuracy. A map measurement is only as good as the method behind it. Rather than imply pinpoint precision, our guides explain where the numbers come from and where they have limits.
- Fast and simple. No tutorials required. If a first-time visitor can't get a measurement in ten seconds, we've failed.
Who runs it
Map Measurer is built and maintained by an independent developer who got tired of clunky measuring tools.
