This page describes products and general use; it is not medical advice.
Who uses this page: clinic and care-home staff, home-care buyers and students who need to know what the dimension lines on a patient lift specification mean, and which of them decide whether a lift fits a room, a doorway or a storage space. Patient lift dimensions are not standardized: they differ between models and even between the electric and hydraulic versions of one model, so the figures below are a worked example from one manufacturer’s manual, not typical values.
What the dimensions on a patient lift mean
A mobile patient lift is, in the words of the FDA’s classification regulation, a hydraulic, battery or mechanically powered device used to lift and transport a patient from one place to another (21 CFR 880.5510, non-AC-powered patient lift). Its specification sheet usually lists many separate measurements. The labels below are the ones used in the Joerns Hoyer Advance user manual (checked 2026-10-30).
| Manual label | What it describes | Where it matters |
|---|---|---|
| Legs Closed – External Width | Overall width of the base with the legs closed | Doorways and passages |
| Legs Closed – Internal Width | Clear gap between the closed legs | Fitting around a chair or wheelchair base |
| Legs Open – External / Internal Width | The same two measurements with the legs spread | Access around armchairs and wheelchairs |
| Overall Height of Legs and Ground Clearance | How tall the base legs are and the gap under them | Whether the base can pass under a bed or chair frame |
| Spreader Bar Max. Height / Min. Height (usable) | Highest and lowest working positions of the spreader bar | Lifting range |
| Maximum Reach | Defined in the manual as the centre of the spreader bar to the front of the mast | How far the load can be held from the mast |
| Turning Radius | Space the lift needs to turn (the manual gives no further definition) | Manoeuvring in rooms |
| Folded Dimensions | Height, depth and width when folded | Storage and transport |
The “where it matters” column is an editorial reading of the labels; the manual itself states the reach definition and its guidance on the legs (see “Does a lift fit through a door?” below). The manual also states that all its measurements are within a +5/-5 degree tolerance.
Example: one lift’s published dimensions, electric versus hydraulic
The Hoyer Advance is published in two versions, and the manual’s technical specifications table lists them side by side. The Safe Working Load is 341 lb (155 kg) for both. Every other row differs, which shows why a single “standard patient lift size” does not exist.
| Specification | Electric | Hydraulic |
|---|---|---|
| Legs closed, external width | 26.3 in (670 mm) | 25.2 in (640 mm) |
| Legs closed, internal width | 22.4 in (570 mm) | 21.7 in (550 mm) |
| Legs open, external width | 42.5 in (1080 mm) | 43.7 in (1110 mm) |
| Legs open, internal width | 39.3 in (1000 mm) | 45.7 in (1160 mm) |
| Overall height of legs | 4.5 in (115 mm) | 4.7 in (120 mm) |
| Ground clearance | 1.1 in (30 mm) | 1.2 in (30 mm) |
| Overall length, minimum to maximum | 49 to 51 in (1250 to 1300 mm) | 47.2 to 49.2 in (1200 to 1250 mm) |
| Overall height, minimum to maximum | 53.5 to 73 in (1360 to 1860 mm) | 53.1 to 72.6 in (1350 to 1845 mm) |
| Spreader bar height, usable minimum to maximum | 15.3 to 66.5 in (390 to 1690 mm) | 15.4 to 64.6 in (390 to 1640 mm) |
| Maximum reach | 32.8 in (835 mm) | 33.5 in (850 mm) |
| Turning radius | 55.9 in (1420 mm) | 41.0 in (1040 mm) |
| Folded (height x depth x width) | 17.1 x 46.4 x 21.6 in (450 x 1180 x 550 mm) | 16.9 x 46.5 x 23.0 in (470 x 1230 x 550 mm) |
| Front twin casters / rear braked casters | 3.0 in (75 mm) / 3.9 in (100 mm) | 3 in (75 mm) / 4 in (100 mm) |
Source: Joerns Hoyer Advance User Manual, section 9, Technical Specifications (checked 2026-10-30). Two details stand out. The hydraulic version turns in a much smaller radius (41.0 in against 55.9 in), and its open legs are far wider on the inside (45.7 in against 39.3 in). Compare the same row across versions: two lifts of one name do not necessarily share a footprint.
Does a lift fit through a door?
The Hoyer Advance manual says the legs can be opened to give access around armchairs or wheelchairs, and that “for transferring and negotiating doorways and passages, the lift legs should be securely locked in the closed position.” So the closed-leg external width is the figure to compare with a doorway; the open-leg width is not.
For a fixed reference, the 2010 ADA Standards for Accessible Design (36 CFR Part 1191, Appendix D, section 404.2.3) require a door opening to have a clear width of at least 32 inches (815 mm). The example lift’s closed external width is 25.2 to 26.3 in, which is less than 32 in. These standards govern the accessibility of buildings, not patient lifts, and a doorway in an older or private building may be narrower, so the measurement of the actual opening still has to be taken.
The ADA also describes a wheelchair turning space as a circle 60 inches in diameter (section 304.3.1). That is a building clearance for a wheelchair, not a lift specification, and it is not directly comparable with the manual’s “turning radius”, which the manual does not define further. Treat the manufacturer’s figure as the lift’s own, and measure the room.
Floor, sit-to-stand and ceiling lifts
This page uses a mobile floor lift as its worked example. Other lift designs, such as ceiling-mounted or sit-to-stand units, publish different sets of dimensions, so use the manual of the exact model. See what a patient lift is for the types.
Specifications to compare
- Capacity: the Safe Working Load is a stated specification (341 lb / 155 kg for the example). See weight limit for a Hoyer lift for why the lowest rating among lift and sling governs.
- Leg position: legs open for access around armchairs and wheelchairs; locked closed for doorways and passages.
- Drive type: electric and hydraulic versions of one model have different dimensions, as the table shows.
FDA classification
Under 21 CFR 880.5510, a non-AC-powered patient lift is a Class I device (general controls) and is exempt from premarket notification, subject to the limitations in 21 CFR 880.9. This describes the regulatory class, not a size requirement: the regulation sets no dimensions.
Common mistakes
- Reading the open-leg width as the width that must pass a door. The manual says the legs should be locked closed for doorways.
- Mixing external and internal width. External width is the outside of the base; internal width is the gap between the legs.
- Assuming ground clearance means a lift can slide under any frame. The example figures are 1.1 to 1.2 in of clearance beneath legs that are 4.5 to 4.7 in tall; check the exact model and the furniture.
- Applying one model’s figures to another. The electric and hydraulic versions of one model already differ.
- Comparing a lift’s turning radius with the ADA 60 in wheelchair turning circle as if they were the same measure.
FAQ
How wide is a patient lift?
It depends on the model and the leg position. For the example Hoyer Advance, the base is 25.2 to 26.3 in wide externally with the legs closed and 42.5 to 43.7 in with the legs open.
Is there a standard patient lift size?
No standard size is set in the FDA regulation or the ADA Standards cited on this page. FDA’s regulation defines the device type and class but sets no dimensions, and the one manual examined shows differing dimensions between its own two versions.
Can a patient lift go through a standard door?
The example lift’s closed width of 25.2 to 26.3 in is below the 32 in minimum clear door width in the 2010 ADA Standards, and its manual says to lock the legs closed for doorways. The actual opening and the actual model still need to be measured.
