Ramp Calculator | How to calculate ramp slope & length?

Before designing your ramp and making the necessary measurements, our excel based calculator needs Rise measurement as input

We also have provided three options in our calculator

OPTION 1: Commercial Properties: Compliance with ADA Standards

While using this option the slope is always 4.8 ° degrees

After You provide the height of the rise and select the unit of measurement.  The sheet will provide the distances for the ramp length and run by using the formula below

Ramp Length (ft) = Ramp Rise (in) {or} Ramp Length (ft) = Ramp Rise (ft) x 12

For Ramp Run

Equation,

Ramp Run2 = Ramp length2 - Ramp Rise2

Therefore,

Ramp Run = √(Ramp length2 - Ramp Rise2)

OPTION 2: Residential Occupied - User is sitting in seat

While using this option the slope is always 10 ° degrees

After You provide the height of the rise and select the unit of measurement.  The sheet will provide the distances for the ramp length and run by using the formula below

Ramp Length (ft) = Ramp Rise (in)/2

For Ramp Run

Equation,

Ramp Run2 = Ramp length2 - Ramp Rise2

Therefore,

Ramp Run = √(Ramp length2 - Ramp Rise2)

OPTION 3: Residential Unoccupied - User is NOT sitting in seat

While using this option the slope is always 10 ° degrees

After You provide the height of the rise and select the unit of measurement.  The sheet will provide the distances for the ramp length and run by using the formula below

Ramp Length (ft) = Ramp Rise (in)/3

For Ramp Run

Equation,

Ramp Run2 = Ramp length2 - Ramp Rise2

Therefore,

Ramp Run = √(Ramp length2 - Ramp Rise2)

Ramp Calculator

We also Have another excel based calculator that will find the slope for any give rise and run.  Please do check it out: Staircase Slope Calculator

Ramp Calculations

1. Consider We have 2 meter Ramp rise (m)

Meter to feet – 1 meter – 3.28 ft

Therefore,

2 meter x 3.28 = 6.561 ft

So,

Ramp Length (ft) = Ramp Rise (in) {or} Ramp Length (ft) = Ramp Rise (ft) x 12

Ramp Length (ft) = 6.561 x 12 = 78.732

Ramp Length (m) = 78.732/3.28 = 24.00m

For Ramp Run

Equation,

Ramp Run2 = Ramp length2 - Ramp Rise2

Therefore,

Ramp Run = √(Ramp length2 - Ramp Rise2)

Ramp Run = √(242 - 22)

Ramp Run = 23.917
