Ramps & Access
How Do You Choose the Right Wheelchair Ramp?
The right ramp is determined by the obstacle, the available space, the user and how permanent the access route needs to be. Start with measurements, not a product name.
01
Quick Answer
To choose a wheelchair ramp, measure the vertical rise, available horizontal run and clear width first. Then check the threshold or step shape, door movement, mobility device, load capacity and whether the ramp will be occasional, portable, relocatable or used as an everyday access route.
Start with the problem
There is no single 'best' wheelchair ramp
A small uPVC doorway threshold, a garden step and a higher external entrance are three completely different access problems. Even if two sites have the same rise, the available approach space, door direction and way the route will be used can change the correct answer.
That is why a useful ramp specification starts with the site and user. A product should be selected only after the geometry and intended use are understood.
Measure before choosing
Six checks can change the ramp you need
01
Vertical rise
Measure from the lower approach surface to the level the wheels must reach. Do not measure only the visible lip if the final landing is higher.
02
Available run
Record the clear horizontal distance available without blocking a pavement, gate, road, path or circulation area.
03
Clear width
Check the narrowest point of the doorway and route against the wheelchair, scooter, walking aid or other equipment being used.
04
Threshold profile
Timber thresholds, uPVC frames and steps create different contact points. Some need a bridge or threshold-specific solution rather than a board resting on the frame.
05
Door movement
An outward-opening door can conflict with the ramp or reduce useful landing space. A platform may be necessary on more substantial routes.
06
User & mobility aid
Manual wheelchairs, powered chairs, scooters, walking aids and assisted users can have different requirements for width, gradient and ramp format.
Match format to barrier
What are the main types of wheelchair ramp?
| Ramp type | Best suited to | What distinguishes it |
|---|---|---|
| Threshold ramp | Small doorway level changes | Compact systems designed around low rises, door sills and threshold profiles. |
| Full-width portable ramp | Steps, temporary access and selected vehicle uses | One continuous surface for the whole wheelchair or mobility aid; folding and multi-fold formats are available. |
| Channel ramp | Portable access where carrying weight and storage matter | Two separate tracks reduce the weight of each individual component, but wheel alignment and device compatibility matter. |
| Relocatable external ramp | Regular outdoor use without a permanently cast concrete ramp | Designed to remain in place more consistently while retaining the ability to be removed or relocated. |
| Modular ramp system | Higher rises and everyday entrance routes | Combines longer ramp runs, platforms and optional handrails into a more complete route. |
| Roll-out pathway | Grass, gravel and difficult approaches | Improves the route leading to a ramp rather than solving the entrance level change itself. |
Frequency of use
From a ramp you carry to a route you use every day
Occasional
Portable
Aerolight-style full-width ramps and Ultralight-style channels can be brought into position when required and stored between uses.
Flexible
Removable threshold
Small threshold solutions may remain conveniently in place or be removed when the doorway needs to return to its usual configuration.
Regular
Relocatable external
Permaramp products are designed for more consistent external access while avoiding conventional permanent construction.
Everyday
Modular route
Welcome modular systems use ramp sections, platforms and optional handrails to create a substantial everyday approach that can still be altered or relocated.
Understand the geometry
Rise, run and gradient are connected
Before comparing ramp products, it helps to understand the three measurements that define the shape of the route. Independent 4 Life's Ramp Calculator lets you enter any two and calculate the third.
YVertical riseThe height difference from the lower surface to the landing or threshold level.
XHorizontal runThe clear distance available for the ramp or complete access route.
1:GradientThe relationship between how far the ramp travels horizontally and how much height it gains.
A calculator is a planning aid, not a product approval.

Ramp length alone does not establish suitability. Check the manufacturer's permitted rise and gradient for the exact model, plus load capacity, mobility-device compatibility, landing space and any requirements that apply to the site.
Real product examples
Why the specification must be checked model by model
Two examples from the current Independent 4 Life range show why generic assumptions are risky. A Welcome modular ramp can form part of a longer everyday access route with platforms and handrails; selected current kits publish a 400kg maximum load. A Permaramp Original is a relocatable external ramp, but its published maximum load changes with length on the current product page.
The lesson is simple: do not assume that all products within a family share the same load rating, permissible rise or installation arrangement. Use the technical data for the exact size and configuration you intend to buy.
Avoid these errors
Common wheelchair-ramp selection mistakes
01
Choosing by step height alone
The same rise can produce very different solutions depending on available run, landing space and doorway construction.
02
Ignoring the door
A ramp can fit the step and still fail in practice if the door cannot open properly or the user has nowhere safe to pause.
03
Forgetting the approach
Grass, gravel or an uneven path can remain a major barrier even when the final step is perfectly ramped.
04
Assuming one load rating
Capacity can vary by model and even by ramp length. Always use the current technical data for the exact configuration.
05
Choosing portability without checking weight
A portable ramp still needs to be handled, moved and stored safely by the people expected to deploy it.
06
Using channels with the wrong equipment
Separate tracks require compatible wheel positions and careful alignment. They are not interchangeable with full-width ramps for every user.
Frequently asked questions
Wheelchair ramp FAQs
How do I know what length wheelchair ramp I need?
Measure the vertical rise and the clear horizontal space first, then use the relationship between rise, run and gradient as a planning starting point. The exact product must still be checked against the manufacturer's permitted rise, gradient and load rating.
Is a threshold ramp the same as a portable access ramp?
No. Threshold ramps are designed for relatively small changes in level at doorways. Portable access ramps are generally used for larger steps or temporary obstacles and may fold or telescope for storage.
When should I consider a modular ramp?
When the entrance has a greater rise, needs platforms or handrails, or will be used as a regular everyday route, a modular system may be more appropriate than a single portable board.
Can I send measurements or photos for help?
Yes. For an awkward entrance, contact Independent 4 Life with clear photographs and dimensions before ordering so the team can help narrow the options.
