Save up to five results to compare changes side by side. Scenarios stay in this tab until you clear or reload it.
Using Grid Path Distance Calculator
Compare Manhattan, diagonal-grid and straight-line distance between grid cells.
- Enter start x, start y, end x, end y using the units printed under each field.
- Choose Calculate, or enable live updates. Review the result labels and formula assumptions.
- Save scenarios to compare up to five variations, then copy the report or download JSON or CSV.
Example
Start X: 0 cells Start Y: 0 cells End X: 7 cells End Y: 4 cells Four-way moves: 11 Eight-way moves: 7 Weighted diagonal distance: 8.6568542 Straight-line distance: 8.0622577
Questions & answers
What does Grid Path Distance Calculator calculate?
Compare Manhattan, diagonal-grid and straight-line distance between grid cells.
Which units should I enter?
Start X uses cells. Start Y uses cells. End X uses cells. End Y uses cells. Convert values to these units before calculating.
Which formula does it use?
Manhattan = dx+dy; eight-way steps = max(dx,dy); weighted diagonal path uses √2 diagonal cost.
What does the included example show?
Start X: 0 cells; Start Y: 0 cells; End X: 7 cells; End Y: 4 cells. Result: Four-way moves = 11; Eight-way moves = 7; Weighted diagonal distance = 8.6568542; Straight-line distance = 8.0622577.
Can I compare different settings?
Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.
Can I export the calculation?
Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
