About Walk Score Estimate Calculator

Walkability scoring combines amenity access with street network quality. Amenities within a five minute walk count most heavily and those within ten minutes count at a reduced weight, together contributing up to seventy points. Intersection density and short blocks contribute the remainder because a fine-grained grid gives direct routes, while long blocks and cul-de-sacs force detours.

Formulas

Amenity component

Score = 6 per amenity within 400 m + 2 per amenity within 800 m, capped at 70

Connectivity component

Up to 20 points for intersection density and 10 for short blocks

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Walk Score Estimate figure worked out?

Score = 6 per amenity within 400 m + 2 per amenity within 800 m, capped at 70. Walkability scoring combines amenity access with street network quality.

Why does intersection density matter?

It measures route directness. A neighbourhood with the same amenities but a coarse network makes every trip longer than the straight line distance, and beyond about 1.3 times, people drive instead.

What values do I need to enter?

This calculator takes 4 inputs: Amenities within 400 metres, Additional amenities within 800 metres, Intersection density, Average block length. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
