A portable ramp can be carried or stored between uses, while a modular system combines ramp sections and platforms to fit a longer route or turn. One EZ-ACCESS 4-foot Singlefold AS example is 29.5 inches wide in use, separates into two 10-pound sections and lists an 800-pound capacity; its PATHWAY HD modular system lists 48-inch usable width and configurable ramps and platforms. These are product examples, so measure the rise, route, doorway and total load and check the rules that apply to the site.
Choose the ramp format after measuring the route. A portable ramp can be easier to store or move, while a modular system can be laid out with separate runs and platforms; neither label confirms that the ramp matches a wheelchair, scooter, doorway or project requirement.
Compare the two formats
| Format | Product example and checks |
|---|---|
| Portable folding ramp | EZ-ACCESS lists its SUITCASE Singlefold AS in 2- to 6-foot lengths. Its 4-foot version is 29.5 inches wide, separates into two 10-pound sections and lists an 800-pound capacity. Check ramp length, total load, transition plates, storage and how it is secured. |
| Modular ramp system | EZ-ACCESS lists PATHWAY HD ramps in 2- to 6-foot sections with 48- or 54-inch clear widths and platforms in several sizes. Its maker describes configurations with turns and switchbacks. Check site measurements, landing space, load, anchoring, drainage and installation instructions. |
Specifications are product-specific. A 29.5-inch-wide portable model, for example, is narrower than the 36-inch minimum clear width in the 2010 ADA Standards for covered ramp routes. Do not infer compliance from a product category or a manufacturer’s general description; compare the exact ramp and installed clear width with the requirements for the project.
Measure the full path first
Record the vertical rise, available run, approach and exit space, door swing, turning area and landing locations. Include the wheelchair or scooter width and length, its total load, and any help needed to position or secure a portable ramp. For an accessible route covered by the ADA Standards, ramp runs have a maximum 1:12 slope, a 36-inch minimum clear width and a 30-inch maximum rise per run; landings are required at the top and bottom and must be at least 60 inches long.
The ADA Standards are not a universal code for private homes. The U.S. Access Board says the ADA does not apply to individually owned or leased private housing that is not used as a public accommodation, while state and local requirements may still apply. Check the applicable rules and the ramp maker’s instructions before selecting or installing a system.
When to compare a modular layout
A modular system can be useful when a route needs more than a single straight ramp, such as turns, intermediate landings or a longer rise. Confirm the layout, landing clearances, handrails, edge protection, surface and water drainage for the exact installation. A qualified access professional can review the path and site conditions; use the manufacturer’s installation instructions for assembly and anchoring.
For slope, landing and handrail dimensions, see wheelchair ramp slope and length. For a small doorway transition, compare threshold ramps and door clearances. For changes between floors, see stairlifts and platform lifts. Browse home access.

Common questions
What is the difference between a portable and modular ramp?
A portable ramp is designed to fold, separate or move between uses. A modular system joins ramp sections and platforms into a site-specific route; sizes and installation details depend on the exact system.
Can a portable wheelchair ramp meet ADA requirements?
A product name does not establish compliance. For covered routes, the ADA Standards include a 36-inch minimum ramp clear width, a maximum 1:12 slope and level landings; check the exact installation and whether those standards apply to the site.
When is a modular ramp worth considering?
A system with sections and platforms may fit a longer or turning route that needs a planned landing. Measure the site and compare the manufacturer's layout, installation instructions and local requirements.
Do ADA ramp dimensions apply to every home?
No. The ADA does not apply to individually owned or leased private housing that is not used as a public accommodation. Local access and building rules can still apply.
