Parking Space Count
A bay itself is about 12.5 m², but with aisles and turning room each car needs 25–35 m². Dividing the lot by that gives a working estimate.

Formula
Parking spaces = Lot area ÷ Area per car
Shape matters as much as area. A long narrow site loses more to aisles and holds fewer cars for the same square metres.

Frequently asked questions
QHow is Parking Space Count calculated?
Parking spaces = Lot area ÷ Area per car — A bay itself is about 12.5 m², but with aisles and turning room each car needs 25–35 m². Dividing the lot by that gives a working estimate.
QCan you walk through an example?
With Lot area 900m², Area per car 30m², the answer is Parking spaces 30.
QWhat do I need to enter?
Enter Lot area, Area per car. The result recalculates as you type, and an empty box counts as zero.
QHow much does the answer move if I change a number?
Changing only Lot area (m²) moves the answer to Lot area (m²) 450 → Parking spaces 15 and Lot area (m²) 1,800 → Parking spaces 60. The table below lays out five steps.
QHow are the numbers rounded?
Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.
QAnything to watch out for?
Shape matters as much as area. A long narrow site loses more to aisles and holds fewer cars for the same square metres.
