What is the Movement Range Grid & How does it work?
In many board‑games and tabletop RPGs, characters move across a square grid. The distance they can travel each turn is usually expressed as a **speed** value, measured in tiles. Understanding how speed translates to reachable squares is essential for tactical planning. Two common distance metrics are used. **Manhattan distance** (|Ξ”x|+|Ξ”y|) counts only orthogonal steps, while **Chebyshev distance** (max(|Ξ”x|,|Ξ”y|)) allows diagonal movement as a single step. The choice of metric changes the shape of the movement range from a diamond to a square. When diagonal movement is permitted, the total number of squares a piece can reach within a speed s forms a square of sideβ€―2sβ€―+β€―1. This relationship can be expressed mathematically, making it easy to calculate the maximum reach without enumerating every tile.
N = (2,s + 1)^2
s = speed (tiles per turn)

Frequently Asked Questions
What is Manhattan distance in this calculator?
Manhattan distance counts only orthogonal steps (up, down, left, right) to determine reachable squares.
How does Chebyshev distance differ from Manhattan distance?
Chebyshev distance allows diagonal movement as a single step, expanding the range of reachable squares compared to Manhattan distance.
Can I use this calculator for both board games and tabletop RPGs?
Yes, the calculator is designed for use in various board games and tabletop RPGs that involve grid-based movement.
How do I input my character's speed into the calculator?
Enter your character's speed value in tiles to see how many squares they can reach on the grid.
What is the difference between orthogonal and diagonal movement?
Orthogonal movement refers to moving up, down, left, or right, while diagonal movement allows for movement at a 45-degree angle.
Can this calculator handle different grid sizes?
Yes, the calculator can be adjusted to accommodate various grid sizes commonly used in board games and tabletop RPGs.
Is there an option to switch between Manhattan and Chebyshev distance metrics?
Yes, you can easily switch between Manhattan and Chebyshev distance metrics to see how it affects your character's movement range.
