How to Choose the Right Wheelchair Ramp for Your Home: A Complete Guide

Hello from the Ramp Pros family!

Making your home more accessible is one of the most meaningful decisions you can make. Whether you’re planning for a family member returning home after surgery, supporting aging parents who want to stay independent, or preparing for long-term mobility needs, the right wheelchair ramp can restore freedom and confidence.

At Ramp Pros, we’ve guided hundreds of families through this process with honest, no-pressure advice. One of the biggest questions we hear is: “How do I choose the right wheelchair ramp for my home?”

In this guide, we’ll walk you through everything you need to know — with special focus on how to accurately measure the rise and how to determine the best ramp size and length. We’ll also cover portable vs. modular options, key safety factors, and how our USA-made aluminum ramps (like PVI portables and Independence modular systems) can fit your situation perfectly.

Step 1: Understand Your Needs

Before measuring anything, ask yourself a few simple questions:

• Who will use the ramp? (Manual wheelchair, power scooter, walker, or occasional use?)
• How often will it be used? (Daily, or just for visits?)
• Do you own your home or rent? (This affects permanent vs. temporary solutions)
• What’s your budget and available space?
• Any special considerations like weather exposure (especially important here in Hawaii with rain and coastal air)?

Answering these helps narrow down whether a portable ramp (quick setup, foldable, storable) or a modular ramp (more stable, semi-permanent, customizable with turns and landings) is better for your home.

Step 2: How to Measure the Rise (The Most Important Measurement)

The rise is the vertical height you need to overcome — from the ground or lower level up to the finished floor at your doorway or threshold.

Here’s exactly how to measure it safely and accurately:

1. Clear the area — Remove any obstacles around the entrance.
2. Use a level tool — A 4-foot or longer level, laser level, or even a straight board with a small level works well.
3. Measure straight up — Place one end of the level or board on the ground (or bottom landing area) directly in line with the doorway. Measure the vertical distance from that point up to the finished floor level inside the door. This is your total rise in inches.
4. For stairs — If you have existing steps, measure the height of each riser (the vertical part of each step) and add them together. Example: Three standard steps at 7 inches each = 21 inches of rise.
5. Double-check — Measure from a few different spots in case the ground slopes. Always use the highest ground point to the door threshold for safety.

Pro Tip from Ramp Pros: Take photos of your entrance from the side and straight on, plus a close-up of the threshold. Send them to us — we can help verify your measurements and suggest the best layout.

Step 3: Determining Ramp Length — The 1:12 Slope Rule

Once you know the rise, you can calculate the minimum ramp length needed for safe, comfortable use.

Recommended Guideline (Best Practice): Use a 1:12 slope — For every 1 inch of rise, you need at least 12 inches (1 foot) of ramp length.

Examples:

• 6-inch rise → Minimum 6-foot ramp
• 12-inch rise → Minimum 12-foot ramp
• 24-inch rise → Minimum 24-foot ramp
• 30-inch rise → Minimum 30-foot ramp

This creates a gentle incline of about 4.8 degrees, which is much easier and safer for manual wheelchairs, power scooters, and assisted use.

For Residential Homes (More Flexible Than Commercial ADA): If space is very limited, some families use a slightly steeper slope like 1:10 or 1:8 (10–12 inches of ramp per inch of rise), but we generally recommend staying as close to 1:12 as possible for daily safety and ease.

A gentler slope (longer ramp) is always better if you have the room — it reduces strain and lowers fall risk.

Step 4: Other Key Factors When Choosing Ramp Size

• Width: 36 inches clear is a good minimum for most home use. Wider (42–48 inches) is better if you have a larger wheelchair/scooter or want easier two-way traffic.
• Weight Capacity: Choose a ramp rated well above the combined weight of the user + wheelchair/scooter (our PVI and Independence ramps often handle 600–1,000+ lbs).
• Landings & Turns: For longer or higher rises, you’ll need level landings (at least 60" x 60" for turns). Modular systems make this easy to configure.
• Threshold Height: Small rises (under 2–3 inches) may only need a simple threshold ramp like our Elev8 Adjustable models.
• Indoor vs Outdoor: Outdoor ramps need excellent slip resistance and weather durability — our aluminum models excel here
