The Measure Tool tool allows you to measure distances on the table by clicking and dragging. You can share the measurement line with other players for discussion or limit visibility to yourself and the GM.

**Changing Measurement Style Settings (GM only)**

You can modify the default grid settings which affect the Measure Tool behavior in the Game Default Settings. Additionally, each page of the campaign can have its own unique settings, which can be accessed and changed in Page Settings via the Page Toolbar.

Besides changing the Measure Tool and grid settings, you can change the scale, the distance units (feet, meters, etc.), and how measurements are calculated.

There are two grid types, Square (default) and Hex, and the grid can be disabled. Your choice of Grid changes the options you have. Hex Grids have the option to show the grid label in each space.

**Square Grids have four options for measuring:**

1. **D&D 5E/4E Compatible** is the default setting. This measures a diagonal move as 1 unit. This simplifies the counting of squares at the expense of realism.

2. **Pathfinder/3.5E Compatible** measures a diagonal move as 1.5 units (rounding down). Thus, when 1 unit equals 5ft, diagonal moves alternate between 5ft and 10ft increments (i.e. 5ft, 15ft, 20ft, 30ft, etc.). This is slightly more complicated to count, but models reality more closely.

3. **Manhattan** measures a diagonal distance as the sum of its horizontal and vertical distances. Effectively, a diagonal move equals 2 units using this method. This is also called "Taxicab geometry" or "rectilinear distance".

4. **Euclidean** measures diagonals using the Pythagorean Theorem. A diagonal move equals about 1.414 units using this method. This is also called the "real distance" or "as the crow flies."

**Hex Grids have two options for measuring:**

1. **Hex Path** measures a diagonal via the shortest path to the destination, adding one unit for each hex a token would have to pass through to reach the endpoint.

2. **Euclidean** measures diagonals using the Pythagorean Theorem. A diagonal move equals about 1.414 units using this method. This is also called the "real distance" or "as the crow flies."
