Quick answer
What are standard commercial elevator dimensions?
A standard commercial passenger elevator has an interior cab of about 68 to 80 in wide, 51 to 68 in deep, and 96 in tall (1.7 to 2.0 m wide, 1.3 to 1.7 m deep, 2.4 m tall), sized by a rated capacity of 2,000 to 4,000 lb. Door openings run 42 to 48 in (107 to 122 cm). ADA sets a 51 by 68 in minimum cab.
Size reference
Commercial passenger cab sizes by rated capacity.
| Rated capacity | Cab width | Cab depth | Cab height | Door width |
|---|---|---|---|---|
| 2,000 lb (907 kg) | 68 in (173 cm) | 51 in (130 cm) | 96 in (244 cm) | 36 in (91 cm) |
| 2,500 lb (1,134 kg) | 80 in (203 cm) | 51 in (130 cm) | 96 in (244 cm) | 42 in (107 cm) |
| 3,000 lb (1,361 kg) | 80 in (203 cm) | 57 in (145 cm) | 96 in (244 cm) | 42 in (107 cm) |
| 3,500 lb (1,588 kg) | 80 in (203 cm) | 63 in (160 cm) | 96 in (244 cm) | 48 in (122 cm) |
| 4,000 lb (1,814 kg) | 80 in (203 cm) | 68 in (173 cm) | 96 in (244 cm) | 48 in (122 cm) |
Capacity classes follow ASME A17.1. The cab interior is the clear inside dimension; the door opening is narrower and is usually the limiting dimension when moving wide items.
Quick lookups
Quick fit-check examples.
Standard commercial elevator size
The most common commercial passenger elevator is the 2,500 lb class, with an interior of about 80 in wide by 51 in deep and a 42 in door. The 3,500 lb class deepens the cab to 63 in for higher-traffic buildings, and office and retail towers typically install the 3,000 to 4,000 lb classes. Measure the door opening, not the cab, when you need to move a desk or sofa.
Commercial vs residential elevator size
A commercial elevator is rated by capacity class and runs 2,000 to 4,000 lb with a 42 to 48 in door, while a private home elevator holds 500 to 1,000 lb with a 32 to 36 in door. The commercial cab is both wider and deeper, which is why a piece that will not fit a home lift often clears a commercial one.
Measure smart
What to measure.
Four numbers decide nearly every fit check. Get these right and the rest follows.
- 01Width, depth, and height of the item, taken at the widest points, including any feet, handles, or protrusions.
- 02The clear opening of every space the item passes through, measured at the tightest point rather than the nominal size.
- 03The item's smallest dimension, which decides whether tilting or turning it on edge gets it through.
- 04Diagonal clearance at turns, landings, and openings, where the real bottleneck usually is.
Don't make these
Common mistakes.
Most “it didn't fit” stories trace back to one of these oversights.
- ⚠Trusting the printed or nominal size instead of measuring the item and the space yourself.
- ⚠Measuring the frame or outer edge instead of the actual clear opening.
- ⚠Forgetting that a long item can sometimes clear a tight space only when tilted or turned.
- ⚠Planning one space and overlooking the next one in the path.

Frequently asked
Questions we keep getting.
What is the standard size of a commercial elevator?
A standard commercial passenger elevator cab is about 80 inches wide, 51 to 68 inches deep, and 96 inches tall, sized by a rated capacity of 2,000 to 4,000 pounds. The 2,500 pound class (80 by 51 inches) is the most common single installation.
01How wide is a commercial elevator door?
Commercial passenger elevator doors are typically 42 to 48 inches (107 to 122 cm) wide. The door opening is narrower than the cab interior, so it is the dimension that limits wide furniture. ADA requires at least a 36 inch (914 mm) door.
02What is the capacity of a standard commercial elevator?
Commercial passenger elevators are rated in classes from 2,000 to 4,000 pounds (907 to 1,814 kg). A 2,500 pound cab carries about 16 people; a 4,000 pound cab carries about 26. Capacity is set by ASME A17.1.
03What are the ADA requirements for a commercial elevator?
ADA requires a minimum cab of 51 inches deep by 68 inches wide for new construction, a door opening of at least 36 inches, and controls reachable from a wheelchair at no more than 48 inches high.
04Will a sofa fit in a commercial elevator?
Most 3-seat sofas (84 inches wide, 35 inches deep) fit in a 2,500 pound or larger commercial cab when stood on end, because the 96 inch cab height clears the 84 inch sofa length and the 42 inch door clears the 35 inch depth. Check the door opening first.
