Diagonal distances are wrong.

In a game, when using the Measure tool to measure a diagonal distance, the distance shown is wrong. Detailed Description of the Problem: Measuring to a space 20ft down and 25ft left, for example, shows a distance of 25ft, whereas it should be 32ft (rounded to the nearest foot). This can be used to cheat the system when making ranged attacks or spells with an area of effect, by measuring distances diagonally to gain extra range. Steps to Reproduce the Problem Using the measure tool, measure any diagonal distance. The distance will be wrong.

Lewis, there are 4 choices of different settings for diagonal measurements of the ruler. The behavior of this can be changed by the GM under Page Settings. The measurement setting you would like is, from the sounds of it, the one called&nbsp; Euclidean . Wiki Docs, <a href="https://wiki.roll20.net/Ruler" rel="nofollow">https://wiki.roll20.net/Ruler</a> <a href="https://wiki.roll20.net/Page_Settings" rel="nofollow">https://wiki.roll20.net/Page_Settings</a> There are four options for measuring diagonals: 1. D&D 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. 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". 4. 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".
