Lawn Mowing Time Calculator
Estimate how long it will take to mow your lawn based on lawn area, mower deck width, and walking speed.
Mowing Time
Mowing time is estimated from the lawn area divided by the effective cutting rate.
Effective Width = Mower Deck Width x 0.85 (accounting for overlap)
Cutting Rate = Effective Width x Walking Speed
Time = Lawn Area / Cutting Rate
Add 15-20% for turns, obstacles, and breaks.
Common mower deck widths:
- Push reel mower: 14-20 inches (35-50 cm)
- Standard push mower: 20-22 inches (50-56 cm)
- Self-propelled: 21-22 inches (53-56 cm)
- Riding mower: 30-42 inches (76-107 cm)
- Zero-turn: 42-60 inches (107-152 cm)
Walking/driving speeds:
- Push mower: 2.5-3.5 mph (4-5.5 km/h)
- Self-propelled: 3-4 mph (5-6.5 km/h)
- Riding mower: 4-6 mph (6.5-10 km/h)
- Zero-turn: 5-8 mph (8-13 km/h)
