Selecting the right ramp size is essential for ensuring safety, accessibility, and ease of use. Whether you're purchasing a ramp for a wheelchair, mobility scooter, or walker, factors like length, incline, and weight capacity play a crucial role. This guide will help you determine the correct ramp size based on your mobility device, home entryway, and vehicle access needs.
1. Measure the Rise (Vertical Height)
The first step in choosing the right ramp is determining the rise, which is the height from the ground to the highest point where the ramp will rest (e.g., a doorstep, vehicle, or elevated platform).
How to Measure the Rise:
- Use a measuring tape to find the vertical height (rise) from the ground to the entry point.
- Note the measurement in inches to help calculate the ramp length.
Example: If the rise is 12 inches, you will need a ramp long enough to provide a safe incline.
2. Determine the Recommended Ramp Length
Ramp length depends on the incline needed for safe access. Use the following guidelines to calculate the ideal ramp length based on the rise:
A. 1:12 Slope (ADA Compliant – Recommended for Wheelchairs & Independent Use)
- Best for: Permanent home access, wheelchair users, and ADA-compliant installations
- Length Formula: 1 foot of ramp per 1 inch of rise
- Example: A 12-inch rise needs a 12-foot ramp
Pros:
- The safest incline for wheelchair users without assistance
- Easier for seniors, individuals with limited strength, or power wheelchairs
Cons:
Requires a longer ramp, so space might be a concern
B. 1:10 Slope (Moderate Incline – Assisted Use or Short-Term Solutions)
- Best for: Assisted wheelchair use, temporary ramps, and areas with space limitations
- Length Formula: 10 inches of ramp per 1 inch of rise
- Example: A 10-inch rise needs an 8.3-foot ramp
Pros:
- Shorter ramp length than 1:12, making it more space-efficient
- Works well for stronger caregivers assisting a wheelchair user
Cons:
- Harder to push a manual wheelchair without assistance
- Not ADA-compliant for public spaces
C. 1:8 Slope (Steeper Incline – Vehicle Ramps & Short-Term Use Only)
- Best for: Loading mobility scooters & wheelchairs into vehicles or small steps
- Length Formula: 8 inches of ramp per 1 inch of rise
- Example: A 12-inch rise needs an 8-foot ramp
Pros:
- Best for vehicle access, such as van ramps or loading scooters into SUVs
- Requires less space, making it useful for portable ramps
Cons:
- Too steep for independent wheelchair users
- High effort for caregivers to push a manual wheelchair
3. Consider Ramp Width & Weight Capacity
A. Ramp Width:
- Most wheelchairs and scooters need at least 30 inches of width.
- Standard ramp widths range from 30-36 inches for better maneuverability.
B. Weight Capacity:
- Choose a ramp that supports the combined weight of the user, wheelchair/scooter, and caregiver (if needed).
- Standard ramps support 600-800 lbs, while heavy-duty ramps can hold 1,000+ lbs.
4. Choose the Right Ramp Type
There are several types of ramps based on usage needs:
A. Threshold Ramps (1-6 Inches of Rise)
- Best for doorways, sliding glass doors, and small steps
- Short and lightweight (rubber or aluminum)
- Recommended Length: 1-3 feet
B. Portable Folding Ramps (6-24 Inches of Rise)
- Ideal for travel, vehicles, and temporary home access
- Lightweight, foldable, and easy to carry
- Recommended Length: 4-8 feet
C. Modular Ramps (24+ Inches of Rise)
- Perfect for permanent home access, decks, and porches
- Customizable with handrails for added safety
- Recommended Length: 8-20 feet
D. Van & Vehicle Ramps
- Designed for loading mobility scooters & power wheelchairs into cars
- Available in single-fold, multi-fold, or telescoping styles
- Recommended Length: 6-10 feet
5. Additional Safety Considerations
- Check Ramp Surface – Opt for non-slip, textured surfaces for better traction.
- Consider Handrails – Modular ramps with handrails provide extra support.
- Storage & Portability – If you travel frequently, choose a foldable or telescoping ramp.
Final Thoughts
Choosing the right size ramp ensures safe and easy accessibility for mobility scooters, wheelchairs, and walkers.
- Step 1: Measure the rise (height).
- Step 2: Choose the correct ramp length based on slope guidelines.
- Step 3: Consider width, weight capacity, and portability.
- Step 4: Select the best ramp type for home, vehicle, or travel needs.
