The average height of a standard warehouse forklift with the mast fully lowered is 7 to 8 feet (2.1 to 2.4 meters) . However, this measurement, known as the Overall Lowered Height (OALH), varies significantly by forklift type and is only one of several critical height dimensions.
Key Forklift Height Measurements
Overall Lowered Height (OALH): The height from the floor to the top of the mast when the forks are fully lowered. This determines if the forklift can pass through doorways, enter trailers, and fit under ceiling fixtures.
Maximum Fork Height: The distance from the floor to the forks at their highest position. This determines how high the forklift can stack pallets.
Overall Raised Height: The height from the floor to the top of the mast when fully extended. Important for avoiding collisions with overhead sprinklers, lights, and beams.
Average Height by Forklift Type
Forklift Type Typical Overall Lowered Height (OALH) Typical Maximum Fork Height
Standard Warehouse (Counterbalance) 7 – 8 ft (85-90 in) 10 – 20 ft
3-Wheel Electric 6 – 6.5 ft 9.5 – 23 ft
4-Wheel Counterbalance 6.5 – 7.5 ft 10 – 18 ft
Diesel Forklift (3-5 ton) 7 – 8 ft 10 – 20 ft
Rough Terrain 7.5 – 9 ft 10 – 30 ft
Reach Truck 6 – 7 ft 20 – 40 ft
Narrow Aisle Forklift 6 – 7 ft 20 – 40 ft
High-Reach Forklift Varies 30 – 50 ft
Real-World Examples
Model Overall Lowered Height Maximum Fork Height
Crown SC 5700 (3-Wheel) 54 – 100 inches 114 – 276 inches
Crown CB 40-50 (4-Wheel) 80 – 134 inches 118 – 238 inches
Hyster H135FT 12.3 ft (147.6 inches) Varies
The bottom line: The average height of a standard warehouse forklift with the mast lowered is 7 to 8 feet. However, this can vary significantly by type, from 6 feet for compact electric models to over 12 feet for heavy-duty units. Always check the Overall Lowered Height for facility clearance and the Maximum Fork Height for stacking requirements to ensure the forklift fits your specific workspace.
