A good construction calculator will help you quickly perform construction-related calculations, such as how much paint is needed for a certain area, what the volume of an area is, how steep a slope is, or how many materials you need for a certain part of a structure.

## How do you calculate rafter length?

Just multiply the rise or run by the appropriate rafter length factor corresponding to your roof pitch. For example, if your roof pitch is 30ﹾ and your run is 2.4m then reading from the table the rafter length factor is 1.15. Multiply this factor by your run which gives your rafter length.

## How do you calculate rafters?

If you are calculating rafter length from the center of the ridge beam (as shown below), you will need to subtract half of the thickness of the ridge beam from the top end of the rafter. For example, if the ridge beam is 1.5 inches thick, subtract 3/4 of an inch from the overall rafter length.

## How do I calculate how much material I need?

Figure out how much fabric you need with this formula:

1. Width of fabric divided by width of one piece equals the number of pieces that fit into width (rounded down to the whole number).
2. Total number of pieces divided by number of pieces that fit into width equals number of rows you need.

## How do you calculate building materials?

Multiply the total height and length of the wall to find the total area. Multiply the width and height of each opening to find the area. Subtract the area of the openings from the total area of the wall. Divide the result by 32.

## How do you calculate number of stairs?

Divide the rise by 6 or 7 inches (15 or 18 cm) to find the total number of stairs. For larger stairs, divide by 6 and for smaller stairs, divide by 7. The total you get is how many stairs your future staircase will have so you can plan accordingly.

## How do you calculate slope of stairs?

How To Calculate Slope Of Staircase

1. Measure the distance of treads (Exclude the width of nosing). If all the treads are uniform in size, measure one tread otherwise you will need to measure all treads.
2. Measure the height of risers.
3. Divide the riser height by the tread width and then calculate the inverse tangent.

## How do you calculate stair height?

So to calculate the number of treads (steps) you will need, we simply take the height to deck measurement and then divide this figure by 175 (rise height). We than take that final figure and subtract 1, as this final figure has given the total amount of rises and not total amount of treads.
