# How do you cut ramp stringers?

4 min read

##### Asked by: Megan Williams

**Use a circular saw to cut triangular stringers based on your rise and slope measurements**. The nominal size of the boards you select depends on the ramp rise. For example, 2- x 6-inch lumber could be used as stringers if the rise is less than 5 1/2-inches; a rise greater than that would require a 2- x 8-inch board.

## How do you cut the angles on a ramp joist?

*So I mark here then I'll cut this angle off. And that will give me the angle to cut my post. Okay we're ready to start cutting the post now I want to have a finished height of 36 inches.*

## How do you calculate the angle of a ramp?

To calculate the angle of the ramp in degrees, **divide your ratio to get a decimal.** **Then take the arc tangent of the quotient using a scientific calculator to get the angle**. For example, a ramp with a 1-to-12 slope yields the decimal 0.083. The arc tangent of this number is approximately 5 degrees.

## How do you measure ramp stringers?

Cut Up The Shed Ramp Lumber

Knowing that, I measured the width of a few of the boards and the average width was 5-3/4″. Multiply that by 10 if you have a 5′ ramp, 8 if 4′ ramp, 12 if 6′ ramp. **The number you get is the length of the stringers**. It will be a little under your whole number measurement but close enough.

## What is a good angle for a shed ramp?

If possible, try to keep the slope around **11 or 12 degrees**. This translates to about 2 inches of rise for every 12 inches of run. Steep ramps can be dangerous when wet, and they can be very problematic for lawn mowers that have low-hanging belly mowers.

## How do you cut angles with slope?

*So you split it you got 15 you cut them both 15 degrees off from 0 boom. Turn you come to this angle. You do another turn so that we get to 90. We have 120 we need a 90 120. And 90 is 30 degrees.*

## What is the maximum slope of a ramp?

The maximum recommended slope of ramps is **1:20**. Steeper slopes may be allowed in special cases depending on the length to be covered (fig. 4). Ramps should be provided with landings for resting, maneuvering and avoiding excessive speed.

## How do you determine ramp length?

Determining Ramp Length:

**Measure total rise (how many inches from lower level to upper level) and divide by the slope**.

## How do you make a 2×4 ramp?

*Four by fours that are a little less than eight feet long. And these four by fours. Rest on top of that notched a 2×4 that is secured to the side of the shed.*

## How long should a ramp be for 2 steps?

The ADA [Americans with Disabilities Act] recommends **1 foot for ramp for every one inch of rise**. Assuming your stairs are a standard height this means you should buy 22 feet of ramp using the Government standard.

## How do you cut a shed ramp board?

*So I used a flat bar to first pry it off before making my cut. Then I used a level in order to make a straight line across the bottom edge of my door. And use my circular saw to make the actual cut.*

## Can you use plywood for a shed ramp?

The outer floor joist of the shed and the added framing lumber have to be cut away to have the same slope as the ramp will have. **Taking the time to make this connection allows the plywood for the ramp to help hold the ramp supports close to the shed**.

## How do you build a 6 foot shed ramp?

*So first I cut one joist. Then use that as the template to cut the other three. Next I cut the ledger to length which is equal to the width of the opening. Then.*

## How do you build a slope ramp for a shed?

*And we built up on the low side. We added braces along the center stagger to give it extra strength. We then measured out and built these cement forms out of these crawl board cylindrical tubes.*
