What is overlap and why does it matter?

Overlap is the percentage of each pass that repeats the previous strip to avoid missed strips of grass. A 10% overlap on a 21-inch deck means each pass only covers about 18.9 inches of new ground. Typical residential mowing uses 10–20% overlap.

What walking speed should I use?

A comfortable push mowing pace is about 2–2.5 mph. Self-propelled mowers typically run 2.5–3.5 mph. Riding mowers or zero-turns vary widely by model; check your owner manual or use 4–6 mph as a starting point.

Does the calculator account for turning at the end of each row?

No. The estimate is based on straight-line pass time only. For small lawns with many turns, add 10–20% to the result. For large open areas, the estimate will be quite accurate.

How accurate is this estimate?

It gives a good baseline assuming a rectangular or open lawn. Obstacles, slopes, wet grass, bagging clippings, and irregular shapes will increase actual time. Use it as a planning guide, not a stopwatch guarantee.

Can I use square meters instead of square feet?

Yes. Select "m²" for area and "cm" for mower width. The calculator converts everything internally before computing.

Summary

Enter your lawn area, mower cutting width, and walking speed to get an estimated mowing time in minutes and hours.

How it works

Enter your lawn area in square feet or square meters.
Enter the cutting width of your mower deck in inches or centimeters.
Set your average walking speed (typical push mower pace is 2–3 mph).
Adjust the overlap percentage to account for strip overlap (10–20% is common).
The calculator divides the lawn area by the effective swath width times distance traveled to estimate total minutes.
Results update instantly in both minutes and hours.
