Wheelchair Ramp Calculator + Caregiver Buying Guide (2026)
Use the free calculator below to figure out exactly what length and weight rating your parent's situation requires — then learn how to measure rise, what slope is actually safe, and the ramps most caregivers and home health agencies buy.
Quick answer. For a doorway threshold (1-2 in. rise) get an aluminum threshold ramp. For 1-2 home steps (~7-14 in. rise) get a 6-foot Singlefold Suitcase ramp. For 3+ steps or vehicle ramps, go to a Multi-Fold 8-10 foot ramp rated 600+ lb. Use the calculator below to confirm.

Standard residential step = ~7 inches. Use direct measurement for non-standard steps.
Recommended Ramp
6 ft
For a 7-inch rise with caregiver assistance.
A 6-foot Suitcase Singlefold ramp covers this. Look for at least 600 lb weight rating.
See matching ramps below ↓Calculations use the slope rules from ADA Section 4.8 (1:12 for accessible independent use) and the National Council on Aging's home modification guidelines. For permanent installations or rises over 30 inches, consult a certified contractor or occupational therapist.
How to Measure Rise (the Most Important Number)
Rise is the total vertical distance the ramp has to climb — measured from the lower landing to the upper landing. Get this wrong by 2 inches and you'll end up with a ramp that's too steep, too short, or both.
The 4-step measurement
- Stand on the lower surface (driveway, sidewalk, garage floor — wherever the wheelchair will start).
- Hold a tape measure vertically against the bottom edge of the upper landing (the porch, threshold, or doorway floor).
- Read the measurement at ground level. That's your rise in inches. Don't measure the step height — measure the total height from the bottom surface to the top surface.
- For multiple steps: measure from the lowest ground surface to the highest landing. Don't add step heights individually; uneven steps or settled concrete will throw the math off.
Common mistake: measuring from the top of the porch tread instead of the lower ground surface. If there's any threshold lip, raised concrete, or weather seal, add it to your rise number. Better to overshoot ramp length than land short.
Rise Over Run: What "1:12" Actually Means
Ramp slope is described as a ratio — rise (vertical inches) over run (horizontal inches of ramp length). A 1:12 ramp means for every 1 inch of vertical rise, you need 12 inches of ramp length. So a 6-inch rise needs a 72-inch (6-foot) ramp at 1:12.
| Slope | Who it's for | Safety read | Example: 7" rise |
|---|---|---|---|
| 1:20 | Best for solo manual wheelchair use | Gold standard. Almost flat. | 140 in. / 12 ft |
| 1:12 (ADA) | Independent wheelchair user | ADA-compliant. Safe for unassisted use. | 84 in. / 7 ft |
| 1:8 | Caregiver-assisted (most common) | OK with caregiver pushing. NOT for independent use. | 56 in. / ~5 ft |
| 1:6 | Occasional power chair use, vehicle loading | Steep. Tip-over risk. Caregiver only. | 42 in. / ~4 ft |
| 1:4 or steeper | Cart/equipment loading only | UNSAFE for wheelchairs. Do not use. | 28 in. / ~2.5 ft |
Which slope should you actually pick?
- 1:12 (ADA) if your parent uses the wheelchair independently, ever — even occasionally.
- 1:8 if a caregiver is always pushing and storage space is tight.
- 1:6 only for occasional vehicle loading with a power chair — never as a primary home ramp.
Safety Checklist Before You Use Any Portable Ramp
✓ Do
- • Check the ramp's lip catches the top landing fully (no gap, no overhang).
- • Confirm the bottom sits flat on the ground — no rocking.
- • Test with full weight before letting your parent transfer.
- • Keep both hands on the wheelchair handles going up and down.
- • Lock the wheelchair brakes at the top and bottom transitions.
- • Sweep the ramp surface clear of leaves, ice, gravel, and water.
- • Replace anti-skid tape every 6-12 months.
✗ Don't
- • Use a ramp wet without anti-skid tape — aluminum is slick when wet.
- • Push your parent down backwards (always face forward going down).
- • Use a 1:6 or steeper ramp without a second person spotting at the bottom.
- • Use a ramp whose weight rating you can't confirm. Check the label.
- • Use a portable ramp on stairs with uneven treads. Get a contractor.
- • Leave the ramp set up unattended where a confused parent might walk it.
- • Skip the threshold ramp at the doorway. A wheelchair caught on a sill can tip.
When to Skip Portable and Call a Contractor
A portable ramp is the right answer for most short-term, short-rise situations. Permanent or modular installations are required when:
- Rise is over 30 inches. Even with caregiver assistance, a portable ramp over 20 feet long becomes harder to deploy and store than it's worth.
- The user is independent in a power wheelchair. Power chairs are heavier and harder to control on portable ramps; permanent with handrails is safer.
- Local code requires handrails. Most jurisdictions require handrails on both sides for ramps over 6 inches of rise with more than 6 feet of length.
- The landing requires turns. Portable ramps are straight. If you need to turn 90° at a landing, you need a modular or custom build.
- The ramp will be used year-round in snow country. Snow-load ratings and ice management aren't designed into most portable ramps.
- You're applying for VA HISA or Medicaid HCBS reimbursement. These programs typically require a professionally installed ramp; portable purchases may not qualify.
Expect $1,500-$4,000 for a modular aluminum ramp install, $3,000-$8,000 for a custom wood ramp with handrails. Some VA programs and Medicaid waivers cover up to the full cost.
Top Portable Wheelchair Ramps — Caregiver Picks
- EZ-ACCESS Suitcase Singlefold Ramp (6 ft, 800 lb rated) The most-recommended single-fold ramp on the market — folds in half like a briefcase with built-in handle, 30-inch usable width. Crosses 1-2 steps, vehicle bumpers, and short stairs. ~$300.
- Silver Spring Aluminum Threshold Ramp (1-3 inch rise) The single best fix for a sliding glass door or interior threshold a wheelchair or walker keeps catching on. Available in 1", 1.5", 2", 2.5", and 3" rises. Anti-skid surface. Installs in 30 seconds. ~$60-130.
- Titan Ramps Multi-Fold Aluminum Ramp (8 ft, 600 lb rated) Folds in 4 sections so it stores in a hall closet. Crosses 3-4 steps comfortably for caregiver-assisted use. Most-bought for porches and back-door entries. ~$400.
- Ruedamann Solid-Surface Aluminum Ramp (4 ft, 600 lb rated) Solid (non-perforated) surface — easier to push a wheelchair on than mesh ramps, especially for one-handed caregivers. Folds in half, 28-inch usable width. Best for 1-2 step porches. ~$200.
- PVI Multi-Fold Ramp (6 ft, 800 lb rated) The ramp most home health agencies buy for in-home patient transfers. 30-inch width, integrated carry handle, premium build. Made in USA. ~$430.
- Heeve 7-Foot Aluminum Folding Ramp Budget-favorite for caregivers who only need a ramp occasionally — for doctor visits or family events. Folds and stores in a car trunk. 600 lb rating. ~$200-280.
- Prairie View Rubber Threshold Ramp (1-6 inch rise) Rubber alternative to aluminum — heavier and grippier, won't slide on hardwood or tile. Good for interior thresholds and patio doors where a metal ramp would scratch. ~$50-200 depending on rise.
- ORFRA Telescoping Track Ramps (Pair) Two separate track ramps that extend independently — best for SUVs, pickups, and vehicles where a single-piece ramp won't fit the wheel base. ~$280-400/pair.
Ramp Accessories Worth Buying
- Anti-Skid Grip Tape Rolls Most ramps lose grip in 6-12 months. Re-tape the high-traffic strip every year for ~$15.
- Ramp Carrying Bag (Heavy Duty) Most ramps don't ship with a bag. Caregivers who travel with the ramp say this is the first accessory to add. ~$40.
- Stander Security Pole & Handle If your parent uses a walker and not a wheelchair, a security pole at the top of the ramp gives them something to grab. ~$140.
- Motion-Sensor Outdoor Light (Battery) If the ramp is at a back door or in low light, a battery-powered motion light prevents nighttime falls. ~$30.

Frequently Asked Questions
Are wheelchair ramps HSA or FSA eligible?
Yes. Ramps qualify as medical equipment under IRS Publication 502 when needed for a medical condition. Save the prescription (if you have one), receipt, and product description. Most caregivers use FSA or HSA funds.
Will Medicare pay for a wheelchair ramp?
Original Medicare (Part A and B) generally does not cover ramps. Some Medicare Advantage plans include a "home modification" benefit up to $500-$1,500 annually. Check your plan's Evidence of Coverage. Medicaid may cover ramps in some states through HCBS waivers.
How do I install a portable wheelchair ramp?
Portable ramps require no installation. Unfold, position with the lip resting on the top step or doorway, and confirm the bottom sits flat on the ground. Threshold ramps slide under a doorway in seconds. Always test with weight before letting your parent use it.
What if I need to rent a ramp instead of buy?
Local durable medical equipment (DME) suppliers and home health agencies rent ramps for $50-150/month. Best if you need it for less than 3 months (post-surgery recovery, hospice). Beyond 3-4 months, buying is cheaper.
Can I deduct a wheelchair ramp on my parent's taxes?
Yes, if it's a medical necessity and the parent itemizes deductions. Medical expense deductions above 7.5% of AGI are allowed. See our guide to caregiver tax deductions for more.
When should I call a contractor instead of buying a portable ramp?
For any rise over 30 inches, for permanent installations, when local code requires handrails (typically rises over 6 inches with more than 6 feet of ramp length), or when the property has uneven landings, curves, or transitions that a straight portable ramp can't handle.
