How do you calculate ramp run length?
How do you calculate the slope of a ramp?slope[ratio] = rise : run.slope[angle] = arctan(rise/run)slope[%] = 100% * rise/run = 100% * tan(angle)
How long should a ramp landing be?
60 inchesLanding Size Length: the landing length must be at least 60 inches without obstruction. Change in direction: if the ramp changes direction, you need a landing with a clear space that is at least 60 inches by 60 inches.
How long should a ramp be for 2 foot rise?
Ramp Calculations According to ADA standard, you'll need a ramp of 1 foot per inch of rise height.
What does 1/14 mean for a ramp?
Calculating The Ramp's Slope 1, the gradient of wheelchair ramps with lengths of over 1,900 milimetres should not exceed 1:14 and should not be less than 1:10. This slope ratio indicates that for every 14 metres across the length of the ramp, the slope height increases or decreases by 1 metre.
How do you calculate inclined length?
The slope length is calculated using the Pythagorean Theorem, where the vertical distance is the rise and the horizontal distance is the run: rise2 + run2 = slope length2.
What is the minimum size for ramp landings?
A top landing at least 36″ deep is required at all built-up curb ramps.
What is an acceptable ramp slope?

How long for a ramp for a 12 inch drop?
A 5 inch rise requires a 5 foot ramp, a 12 inch rise requires a 12 foot ramp and so on. The ADA recommends this slope for long home ramps as well as commercial ramps.
What does 1/12 mean for a ramp?
For a ramp the maximum running slope allowed is 1:12. That means for every inch of height change there should be at least 12 inches of ramp run.
What is too steep for a ramp?
The Life Safety Code allows some classes of ramps to have a slope as steep as 1:8 (7.1 degrees). Both the Life Safety Code and the National Safety Council recommend that ramp slopes do not exceed 7 degrees.
What is the ratio for a ramp?
1:12What is the maximum gradient for a wheelchair ramp? The ramp must have a 1:12 slope ratio. This means that there must be a one-inch rise in the ramp for every corresponding 12 inches of the ramp.
What is the ramp formula?
Slope expressed as a percentage = (h/d) x 100 An existing ramp of 1 meter in height with a horizontal distance of 10 meters, will have a slope of 10%.
How do you find the rise and run length?
The slope length is calculated using the Pythagorean Theorem, where the vertical distance is the rise and the horizontal distance is the run: rise2 + run2 = slope length2.
How do you calculate run over rise?
All you need to do is calculate the difference between the two points in the vertical direction (rise) and then divide it by the difference in the horizontal direction (run).
How do you calculate Run slope?
To calculate percent slope, divide the difference between the elevations of two points by the distance between them, then multiply the quotient by 100. The difference in elevation between points is called the rise. The distance between the points is called the run. Thus, percent slope equals (rise / run) x 100.
How long should a ramp be for a 36 inch entryway?
For example, if an entryway is 36 inches high, you will need a ramp that is at least 36 feet long. The 1:12 slope ratio reduces the steepness of a ramp to 5 degrees of incline and makes it both easier and safer to traverse.
What is the slope ratio for a ramp?
While the ADA requirements only apply to commercial ramps, many home access professionals adhere to the 1:12 slope ratio for residential ramps as well. However, a slope ratio of 2:12 is also acceptable for residential ramps if space is limited. This means 12-inches of ramp for every 2-inches of rise and 9.5 degrees of incline.
How much slope is required for a commercial ramp?
This often results in a very steep ramp that may resemble a ski jump! The Americans with Disabilities Act (ADA) requires a 1:12 s lope ratio for commercial ramps (ramps used in public spaces). This means that for every 1 inch of rise, 12 inches of ramp are required.
What is a qualified ramp provider?
A qualified ramp or home access provider will be able to evaluate your space and determine what configuration and length of ramp will work best.
Is it better to have a wheelchair ramp or a shorter ramp?
If you plan to add a wheelchair ramp to your entryway, you may be wondering how long it needs to be. Some people might think a shorter ramp is better because it takes up less space and may cost less money. However, if you add a ramp that is too short for the rise of the entryway being ramped, it can be both hard to use and a safety hazard.
How long should a wheelchair ramp be?
The wheelchair ramp slopes should be 12 inches long for every inch of slope or elevation. For instance, a wheelchair ramp for a 24″ rise requires a minimum ramp length of 24′. This enables a low 5-degree incline for convenience ...
What is the slope ratio of a wheelchair ramp?
According to ADA guidelines for ramps, commercial ramps should have a 1:12 ramp slope ratio, whereas residential ramps can have a ratio of 2:12 or 3:12. To make your decision, consider how the wheelchair ramp will fulfill the needs of the users.
Why is ramp length important?
This is because it can affect a person’s safety, ease of use, and convenience.
Where are wheelchair ramps measured?
Finally, the wheelchair ramp slopes are measured diagonally from the top of the steps to the floor where the wheelchair ramp ends. If you’re building a wheelchair ramp, however, you must also consider the measurement of the handrails on either side of the ramp segment.
How to determine the length of a ramp?
To determine the ramp length, you must first establish the measurements required for the steps to which the ramp will be attached. The total vertical rise is the distance between the bottom of the steps to the top of the stairwell. The horizontal distance between the top of the steps and the bottom of the ramp is measured without obstructions.
What is the slope ratio for a ramp?
Apart from that, a 2:12 slope ratio is used in most residential ramps with limited space or area. This is recommended for wheelchair users who want to be able to climb up without assistance.
What is the maximum slope angle for a ramp?
Other recommended maximum slope ramp degrees include a 7-degree angle for users who can use the ramp independently or with light help, 10-degrees for users who require moderate support, and a 12-degree angle for users with powerful electric wheelchairs or scooters, or for those who need strong assistance.

How to measure total rise?
Measure total rise (how many inches from lower level to upper level) and divide by the slope.
How do you calculate the slope of a ramp?
Before we show you how to calculate the slope of a ramp, we first need to explain slope unit convention. You can express slope in many ways, but let's focus on the three most popular forms:
How to find slope ratio?
slope [ratio] = rise : run. Angle. It's the angle between ramp and run (or, in other words, angle of inclination to the horizontal). This angle is commonly expressed in degrees, though other angle units are possible. To calculate the slope's angle, use the inverse tangent: slope [angle] = arctan (rise/run) Percentages.
What is ADA ramp slope?
ADA ramp slopes. The 2010 ADA Standards (Americans with Disabilities Act) set out some minimum requirements for new public facilities. As well as including many different accessibility standards, it contains guidelines for ramp construction. In this paragraph, we'll take a closer look at ADA ramp slopes.
What is the maximum slope of a ramp?
1:12 is the maximum slope of a ramp for new constructions. 1:16 is the comfortable slope. 1:20 is the minimum slope - below that value it's not considered a ramp (thus e.g., handrails are not needed) In each case, the maximum rise allowed is 30 inches (760 mm).
What is 100% slope?
Giving the grade (slope) as a percentage is the most common way of describing slopes in the US and in Europe. Be careful - a 100% slope is not an equivalent to 90 degrees, but to 45 degrees. It's calculated from the tangent of the inclination angle:
What is the minimum landing size for a ramp?
You need to provide enough space for maneuvers: if the ramp construction changes direction (a 90 degree turn), then the minimum landing size is 60"x60":
How long should a ramp be?
For two ramps of equal length, each should be 23.38 ft long. Of course, you can split it differently, depending on the space available. Just remember that for such slope, the maximum distance between landing sites is 40 ft.
How long are handi ramps?
Needless to say, we favor our own Handi-Ramp Modular Portable Wheelchair Ramps. Available in lengths from 12 to 18 feet, the ramps come in interlocking sections each weighing under 35 pounds. Included are support legs that provide excellent stability and confidence that’s simply missing from portable folding ramps. While the initial investment might be a bit more, the Handi-Ramp modular wheelchair ramps come with a 20 year warranty. Our ramps also feature heavy duty aluminum Handi-Treads flooring with our patented, 360-degree traction buttons. Unlike most portable ramps that rely on grit tape for traction, Handi-Ramp modular ramps provide excellent traction in rain, ice or snow and can be cleared with a snow shovel when necessary.
How much does a 10 foot ramp weigh?
To provide safety and strength, longer folding ramps can be quite heavy. For example, our 10 foot ramp weighs 82 pounds and the 12 foot ramp weighs nearly 100 pounds. The price of quality is weight, and there’s no stronger portable folding ramp on the market than these.
What is a modular ramp?
A modular ramp provides the safest wheelchair and walker access for a 3-step rise. On the other hand, if you need a ramp for a set of three or more stairs, a modular ramp is the safest, longest-lasting solution.
How long does it take to disassemble a wheelchair ramp?
Some modular wheelchair ramps, like ours, can be assembled by two people without hand tools in under thirty minutes. Other modular ramps require wrenches or ratchets to tighten bolts and to cinch up sections.
How heavy is a 10 foot folding ramp?
To provide safety and strength, longer folding ramps can be quite heavy. For example, our 10 foot ramp weighs 82 pounds and the 12 foot ramp weighs nearly 100 pounds. The price of quality is weight, and there’s no stronger portable folding ramp on the market than these.
How long is a single fold ramp?
A third choice is the EZ Access Suitcase® Singlefold Ramps. This ramp is available in an 8-foot length, which is the minimum length we might recommend for three short steps with a combined rise of 16 inches or less which is slightly higher than two standard steps. The recommendation of 8 feet assumes that the person in the wheelchair will always be attended by a helper. If a person in a wheelchair is to navigate the ramp on their own, a longer ramp will be required.)
What are the advantages of modular ramps?
Modular ramps have several advantages in these situations. First, they come in longer lengths (12 feet or more) making them much safer for a three step rise. Second , their interlocking construction and adjustable support legs provide more stability than a folding ramp.
