When planning for a new lift, one of the first and most important questions is: what size should it be? The answer isn’t always straightforward. Lift dimensions vary depending on the type of lift, the building type, how many lift users are expected, and whether the installation is part of a new development or an existing building.
Getting this right is about more than making the lift fit. The correct lift size affects safety, accessibility, compliance, and long term reliability. In this guide, we’ll explore standard UK lift sizes, the requirements for passenger lifts, platform lifts, and the practical considerations that ensure lift projects succeed.
The figures below are the sizes you will encounter most often in UK buildings. Treat them as a planning guide rather than a specification. Before any lift installation proceeds, the shaft, headroom and pit need measuring on site, because the gap between a standard size and what a building will physically accept is where most projects run into trouble.
Why Lift Dimensions Matter
The size of the lift car determines how well the lift performs its role within a building. Poorly specified lifts can cause bottlenecks (delays and queues at busy times), fail accessibility tests, or require costly alterations later.
Some of the main reasons dimensions are so critical include:
Accessibility and compliance
Regulations such as BS EN 81-70 and Part M of the Building Regulations set minimum requirements for lift car sizes and door openings. For example, lifts must be the right size to accommodate wheelchair users safely and comfortably.
Functionality and efficiency
In commercial buildings, undersized lifts can’t cope with passenger traffic. Oversized lifts, meanwhile, may be unnecessarily expensive to run.
Building type
Different building types require different lift solutions, what works for a busy shopping centre won’t be the same as for a school or office.
Future proofing
Choosing the right dimensions ensures the lift remains practical even if the building’s use changes or demand increases.
Passenger Lift Dimensions
Passenger lifts are the most common type, used in offices, hospitals, residential developments, hotels and more. They are designed to carry groups of people between floors and are sized according to both rated load (kg) and indicative persons.
Typical Passenger Lift Sizes (BS EN 81-70)
| Car Size (mm) | Rated Load (kg) | Persons (approx.) | Common Uses |
| 1100 × 1400 | 630 | ≈8 | Small offices, mid-rise apartments |
| 1400 × 1600 | 1000 | ≈13 | Care homes, schools, busy commercial sites |
| 1100 × 2100 | 1000 | ≈13 | Public buildings, hospitals (extra depth) |
| 2000 × 1400 | 1275 | ≈17 | Shopping centres, healthcare, high-traffic sites |
*Persons are indicative only, assuming ~75 kg per person.
Platform Lift Dimensions
Platform lifts are designed to provide step free access in situations where the space or structure of the building does not allow for a full passenger lift. They are often installed in schools, offices, heritage properties, or existing buildings with limited space.
Example Platform Lift Sizes (Part M / EN 81-41)
| Platform Size (mm) | Capacity | Travel | Notes |
| 900 × 1400 | ~250 kg | Open platforms ≤ 2 m | Minimum size for a single wheelchair user (Part M) |
| 1100 × 1400 | ~300 kg | Enclosed (model-dependent, up to 12–15 m) | Meets accessibility guidance for most users |
| 1100 × 1500 | ~400–500 kg | Enclosed (model-dependent, up to 12–15 m) | Provides space for a wheelchair user plus carer |
Why Choose a Platform Lift?
- Compact and space efficient
- Suitable for wheelchair users
- Requires less pit depth and headroom clearance than a standard passenger lift
- Can be retrofitted into existing buildings without major structural alterations
Residential and Through Floor Lifts
Although this guide is mainly looking at commercial buildings, residential lifts are worth mentioning. These compact lifts are often used to improve accessibility in private homes or small developments.
Typical Residential Lift Sizes (manufacturer footprints)
| Lift Type | Car Size (mm) |
| Compact | 900 × 1200 |
| Standard | 1100 × 1400 |
| Larger | 1480 × 1480 |
Residential lifts do not always meet the same compliance requirements as passenger lifts in public or commercial buildings. If a lift is used in a shared space, it must meet Part M and BS EN 81-70.
Goods and Specialist Lifts
Some projects require more than just moving people. Goods lifts and combined goods/passenger lifts are designed for heavy loads such as trolleys, pallets, or hospital stretchers.
Common Sizes (HTM 08-02 Healthcare Guidance)
| Car Size (mm) | Door Width (mm) | Load (kg) | Use |
| 2000 × 1400 | 1100 | 1275 | General passenger lift for hospitals and public buildings |
| 1400 × 2400 | 1400 | Model dependent | Stretcher / trolley lift |
Measuring for Lift Installation
Accurate measurement ensures the chosen lift fits the space safely and efficiently. The main areas to measure include:
- Lift shaft dimensions – internal width, depth, and height
- Pit depth – required to keep the lift car level with the lowest floor
- Headroom clearance – the vertical space above the car at the top landing
- Door openings – by EN 81-70 car type:
- Type 1 ≥ 800 mm (existing building allowance)
- Types 2–4 ≥ 900 mm
- Type 5 ≥ 1100 mm
In existing buildings, measurements must often be adapted around structural limitations, making professional guidance essential.
Custom Lift Dimensions
Not every project suits a standard lift. In older or unusual properties, custom solutions may be the only option.
When Customisation is Needed
- The available lift shaft is too narrow
- The size of the building or its usage demands larger than standard capacity
- The lift must fit a very specific operational role (e.g. stretcher lifts in hospitals)
Bespoke lifts can be designed to balance safety, compliance, and the unique constraints of the project.
Installation and Maintenance Considerations
Choosing the correct lift size is just one part of a successful installation. Long term performance also depends on:
- Professional installation – ensuring the lift is installed correctly and safely
- Ongoing servicing and inspections – lifts must be serviced regularly and undergo statutory LOLER thorough examinations every 6 to 12 months depending on use
- Modernisation – upgrading older lifts with new controls, safety features, or reconfigured doors can extend service life and bring them in line with current standards
A lift is a long term investment, so considering its lifecycle from the start is vital.
Planning A Lift Installation?
Knowing the standard dimensions is the easy part. Confirming what your building will actually take, and specifying a lift that fits it, is where a site survey earns its money. Our engineers have been installing lifts across the UK for more than 30 years, in everything from converted mills to new build offices.

Key Takeaways
- Lift dimensions must align with the type of lift, the building type, and the expected number of lift users.
- Passenger lifts typically range from 1100 × 1400 mm (630 kg) up to 2000 × 1400 mm (1275 kg) depending on type.
- Platform lifts provide an accessible, space saving option, particularly in existing buildings (sizes per Part M; travel limits per EN 81-41).
- Residential lifts are suitable for private homes but differ from commercial standards.
- In hospitals and healthcare premises, NHS guidance (HTM 08-02) recommends a general passenger lift size of 2000 × 1400 mm with 1100 mm doors and a 1275 kg load rating.
- Accurate measurement of the lift shaft, pit, and headroom is essential before installation.
- Customisation is available for projects where standard lift sizes won’t work.
