Calculate Wheelchair Ramp Length Requirements (Option C)
Ramps that are too steep are dangerous and unusable for manual wheelchair users. Calculate required ramp length from vertical rise and standard slope ratios. (Option C scope).
1 · entrance step | vertical rise cm | slope ratio cm per meter

Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Data note: Everything runs in this browser tab on the rise-ramp gauge: your entrance step | vertical rise cm | slope ratio cm per meter stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Perspective: Before: Steep slopes cause wheelchairs to tip backward or lose control downhill. After: the rise-ramp gauge shows the working beside each named row so the reader can change the assumption and inspect the consequence.

Free tier
- one complete rise-ramp gauge run in the app
- three samples plus unlimited article-demo runs
- unwatermarked result text and an explicit, user-triggered state link
What $4 one-time adds
- print the rise-ramp gauge with its row workings
- CSV of total ramp length meters and row explanations
- last five reading summaries saved in this browser profile
$4 once for repeated filing of the rise-ramp gauge, not for a better answer. Illustrative time basis: avoiding one five-minute manual reformat per saved reading; no market-price or guaranteed-savings claim.

Boundary and sources
Dimensions arithmetic based on rise measurements and slope ratios. Not structural engineering advice.
- Method: Ramps longer than 6 meters require intermediate resting landings.
- All sample records are invented examples. The app does not fetch measurements, policies, files or personal records.
- Google’s official pricing page, fetched 2026-09-29, lists free-tier access including AI Studio. Optional formatting only; limits and availability can change. Free-tier content may be used to improve products. Never paste private records there.
Mechanism: competence-autonomy-loop
Optional AI formatting, not calculation
For this rise-ramp gauge, use the free AI Studio interface only if available to you, with no paid API key. Manual entry completes the same workflow for free. Supply only fictional or non-sensitive notes. Review its output against the source; never paste unresolved questions into the numeric rows.
Format my non-sensitive notes for a rise-ramp gauge. Return plain rows only: entrance step | vertical rise cm | slope ratio cm per meter. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
Accepted schema: entrance step | vertical rise cm | slope ratio cm per meter. No AI response is executed as code.
