A fast, stripped-back site calculator for patios, drainage, paths and groundworks. Work out fall, reverse fall, ratios and marker drops instantly.
Standard mode uses total run and total fall. Reverse mode is ideal when you already know the full fall and want marker drops. Ratio mode works from a 1:X gradient.
| Marker | Distance | Cumulative Drop | Rounded Site Drop |

Rounded figures are usually easier to mark out with a tape, laser or string line. Always check the required fall for your actual job.
