The Mowing Rectangle calculator estimates the distance walked, calories burned and time required to mow an area of grass based on the length and width of the rectangular area, person's weight, width of mower, mower speed and whether riding or pushing the mower.
INSTRUCTIONS: Choose units and enter the following:
- (L) Length of Area
- (W) Width of Area
- (M) Your Weight (used for calorie calculation)
- (w) Width of Mower (cutting swath)
- (ms) Mowing Speed (default of 3 mph: human walking average)
- (RP) Riding or Push Mower
Miles Walked Mowing (eM): The calculator returns the distance traveled while mowing in miles, the area in acres, the time it took in minutes, and the calories burned. However, these can be automatically converted to compatible units via the pull-down menu.
Useful Stats
- Humans walk at a rate of approximately 3 miles per hour, ranging from 2.1 for women over 80 to 3.2 for men in their 30's
- 4 miles per hour (mph) is considered a good speed for a riding mower. 5.5 mph is considered very fast with an upper limit of 7 miles per hour.
- Most push mowers cut 21" wide swaths.
- Riding mower range from 36" to 54" for larger zero turn mowers.
According to a report from Valdosta University, the following calories per hour are associated with mowing (cutting) grass. These are approximate numbers based on the person's weight, and there are numerous other factors that can change the total calories burned.

The Math / Science
Very few yards are perfect rectangles. In order to estimate the distance walked while mowing, one must first estimate the total mowing area. This calculator uses the width of the swath created by the mower to then compute the linear distance walked. Most push mowers are between 18" and 24" wide. This calculator assumes that there is an overlap of two inches (2") when mowing rows.
- Mowing Calculator: Estimates the distance walked, area covered, calories burned mowing and time required to mow an area of grass based on mower cutting deck width, speed and whether its a push mower or riding mower.
- Lawn Spreader Calculator: Computes the number of bags of lawn treatment (grass seed, weed killer, lawn fertilizer) are needed for a lawn based on the manufacturer recommended area of coverage per bag and the area of the lawn.
- Lawn Spreader Triangle: Computes the number of bags of lawn treatment needed for a triangular lawn based on the manufacturer recommended area of coverage per bag and the length of the three sides of the lawn.
- Lawn Spreader Rectangle: Computes the number of bags of lawn treatment needed for a rectangular lawn based on the manufacturer recommended area of coverage per bag and the length and width of the lawn.
- Lawn Spreader 4 Sided (non-Square): Computes the number of bags of lawn treatment (grass seed, weed killer, lawn fertilizer) needed for a four sided lawn based on the manufacturer recommended area of coverage per bag and the length of the four sides and diagonal of the lawn.
- Lawn Spreader 5 Sided:: Computes the number of bags of lawn treatment (grass seed, weed killer, lawn fertilizer) needed for a five sided lawn based on the manufacturer recommended area of coverage per bag and the length of the five sides and two diagonals of the lawn.
- Grass Seed Calculations use SPREADER calculators above with the grass seed specifications from the manufactures.
