Portable Threshold Ramp for Doorways — Roll-Up vs. Fixed
Not every access barrier requires a long ramp. Doorway thresholds and small interior or exterior transitions — typically 3–8 cm high — call for a compact, targeted solution rather than a construction project. A portable threshold ramp bridges the gap at a balcony door, interior doorway or raised step on a terrace without any installation, without drilling and without altering the building fabric. The MIOR ROLL in compact configuration is designed precisely for this type of situation.

The situation
You have a raised threshold at an interior or exterior doorway — typically 3–8 cm (1–3 in). This may be at a balcony door, a bathroom entrance, a patio doorway, or a low step between rooms. A full-size ramp is too large and impractical. You need a compact, portable threshold ramp that bridges the gap from both sides — entry and exit — for a wheelchair, rollator, walking frame or mobility scooter.
Why measuring matters
Threshold transitions are common in European apartments, older buildings, care facilities and rental properties. Even a 3–5 cm raised threshold can block a manual wheelchair or cause a rollator to tip. A compact threshold ramp avoids permanent modification — critical for renters, listed buildings and anyone needing a flexible solution across multiple doorways or locations. For a 5 cm threshold, the 1:12 reference gives 60 cm of ramp per side — the MIOR practical indication for a compact double-sided solution is 1.0 m total (50 cm up, 50 cm down).

These examples are intended as practical MIOR indications. The correct ramp length depends on the exact height, available space, user, mobility aid and intended use. For more comfortable or guideline-aligned use, a longer ramp may be needed.
How to measure correctly
Step 1: Measure the threshold height — from the lower floor surface to the top of the raised threshold. Step 2: Measure available floor space on both sides of the threshold — entry and exit. Even 30–50 cm on each side is enough for a compact threshold ramp. Step 3: Check the floor type on both sides — hard floor (tiles, wood) or soft (carpet, vinyl)? This affects grip. Use WEXAR to digitally capture the threshold height and surrounding space via smartphone.
Measure with WEXAR
WEXAR measures your threshold height and available floor space on both sides of the doorway — via smartphone, free, without an appointment. For compact threshold situations, WEXAR helps confirm whether a threshold ramp or a longer portable ramp is the better fit. The measurement can also support a local funding application if you are applying for accessibility support. WEXAR helps you capture height, available space and slope on your smartphone. The result is intended as a digital indication and preparation tool. For formal ADA assessments, insurance reimbursement decisions or permanent structural modifications, review by a qualified professional or occupational therapist is recommended.

The MIOR ROLL in compact configuration bridges doorway thresholds and small interior or exterior transitions. The aluminium profile is lightweight, anti-slip on the surface and thin enough to fit under most standard doors. No installation required — place it, use it, roll it up and move it to the next doorway if needed. Suitable for wheelchairs, rollators, walking frames and mobility scooters. For wider doorways or thresholds higher than 8 cm, contact MIOR for advice on the appropriate configuration.
No installation. Portable aluminum threshold ramp for doorways and balcony transitions.
Frequently asked questions
What is the difference between a threshold ramp and a full wheelchair ramp?
A threshold ramp bridges small transitions of 3–8 cm at doorways or interior barriers. A full wheelchair ramp covers larger height differences at steps or stairs. The right choice depends on your barrier height and available space — use the MIOR calculator to confirm which applies to your situation.
Do I need to drill or permanently mount a threshold ramp?
No. The MIOR ROLL portable threshold solution lays flat at the threshold and can be moved or stored as needed. No drilling, no adhesive, no tools required. Ideal for rental properties and listed buildings.
Can a threshold ramp be used from both sides of a doorway?
Yes. The MIOR compact configuration provides a smooth transition from both the entry and exit sides of the threshold. Measure the space available on each side before choosing the total ramp length.
Is a threshold ramp sufficient for a powered mobility scooter?
For small thresholds of 3–5 cm, a compact threshold ramp is typically sufficient for most scooters. For thresholds above 6 cm, or for heavier scooters, verify the slope is manageable using the calculator — or contact MIOR for a specific recommendation.
Can I use a threshold ramp on a carpet floor?
The MIOR ROLL anti-slip surface provides grip on both hard and soft floor surfaces. On thick carpet, the ramp edge may lift slightly — check that the transition is smooth before use. Contact us if you need advice for specific floor conditions.
Can a threshold ramp be moved between different doorways in the same home?
Yes. The MIOR ROLL is fully portable — roll it up, carry it and place it where needed. If you have multiple thresholds to cover, a single ramp can be moved between locations. Consider ordering one per doorway for permanent day-to-day convenience.
