Wheelchair Ramp Plans & Design Resources

Use ramp plans to prepare questions for a qualified installer, not as a substitute for a site assessment.

A drawing that works at one entrance may be unsuitable at another. Rise, available space, door swing, drainage, ground conditions and the intended mobility device all affect a safe route. Local requirements and whether accessibility standards apply must be checked for the actual project.

Start with reliable design references

The U.S. Access Board guide to ramps and curb ramps explains slope, rise, landings, clear width, handrails and edge protection. It is a standards guide, not a set of approved construction drawings for your home.

Understand the space calculation

At a 1:12 reference slope, each inch of rise requires twelve inches of horizontal run. For example, a 12-inch rise requires 12 feet of run before allowing space for landings and turns. A layout must also allow safe access to the doorway. Use our calculator to explore that relationship, then have the site assessed.

Questions before choosing a plan

• Who will measure the entrance and check permits and local requirements?
• How will the ramp meet the landing and support requirements for the site?
• Will it be permanent or removable, and who is responsible for maintenance?
• Can the user and their mobility device navigate the turns, doorway and surface?
• What inspection or professional review is needed before use?

Plans and financial help are different

If you need help obtaining or installing a ramp, use the ramp assistance directory. Some resources offer portable ramps, some coordinate construction, and others provide funding. Confirm the service area and exact help offered before relying on a listing.
