Steps to building a staircase

There are several steps involved in building a set of indoor stairs. For example, it can be difficult to build a staircase without an accurate measurement of the size of the stairs’ risers and treads. You will need to measure the width of the stair treads and risers, and use a framing square to make accurate measurements. Then, you should clamp a pair of stair gauges to the edge of the square, which will help you determine the size of the stringer and the width of each rung.

First, determine the height of your stairway. Measure from the top landing of your room to the finished floor. To do this, you need to measure 118 inches from the top to the bottom. Divide that measurement by 7.5. This will give you the number of risers and treads you need. Once you have this measurement, you should mark the top of the board with a tape measure. Once you have the exact height, you can measure the length of the stair.

Once you’ve measured the distance between the handrails and the treads, you can plan the design of the stair. Before you start building, make sure the stairs are constructed properly. The construction material will affect the overall design of the stair. Using high-quality materials ensures a quality job. Cheap materials may have knots and voids that will cause problems later. A good lumberyard should have plenty of stairs in stock.

Before you begin building the stair, make sure your stair stringers and treads are built according to building codes. Select oriented strand board that is 3/4-inch thick for treads and 2×6 lumber for the risers. Remember to check local building codes before building your stairs. Once you have this set up, you can now start building your stairway. It’s easy, especially if you follow building codes.


When constructing indoor stairs, there are several different materials to consider. Choose high-grade materials to get a quality job. While cheaper materials will look great when covered with carpet, they may contain voids and knots. In the long run, this could lead to cracks and leaks. Most lumberyards have stock of stairs for any type of indoor space. Depending on the look you want to achieve, you can find various materials for indoor stairs at a reasonable price.

Wood is a classic choice for stairs. Wooden stairs can be used indoors and outdoors, but you should note that certain species are not suitable for the outdoors. You need to choose the correct species, saw it properly, and install it. Different woods provide different aesthetics, so make sure to check out the characteristics of each type before you purchase a staircase. If possible, select a variety of species to get a unique look.

The main difference between wood and metal stairs is the material used for the treads and risers. The treads form the walking surface, while the risers are the vertical surfaces between them. The stringer is the support beam of a stair, which can be solid or hollow, or can be a single piece. The stringer is a piece of wood or steel that supports the weight of the stairs and ensures that it remains stable.

Vinyl flooring is another great option. It is a relatively inexpensive option and has the added benefit of being easy to clean and durable. Another option is vinyl, which comes in sheets, tiles, or planks. All of these materials have their advantages and drawbacks. Vinyl flooring can also be noisy and slippery, so choose carefully. When installing vinyl stairs, make sure to cover the edges with a plastic nose to prevent splinters and sharp edges.

Calculating stair rise

When building indoor stairs, you need to know the exact measurements of the stair rise. To calculate the rise, you need to know the distance from the finished floor to the first floor, or the height between the upper finished floor and the landing. Divide this distance by the number of risers you want to use. If you use one-inch increments, you should round these numbers to the nearest whole number. In this way, you will get the exact height of each stair.

The best way to calculate stair rise and run is to use a stair calculator. There are several free online stair calculators, and you can even use one for your own home. These calculators will help you determine how high your stair rise must be to meet building codes. You can also find a stair calculator that is built for non-standard sizes and terrain. This way, you can be sure your stairs are safe for everyone and comply with building codes.

The calculator also helps you in engineering related subjects, like air change rates. The stair rise will determine how many tread pieces you will need and how much railing you will need. You can use the same calculator to calculate air change rates in buildings and rooms, which is useful for calculating the air circulation rate in these areas. Once you have determined the rise and run, you can calculate the rest of the stair’s components, such as the stair treads.

When calculating stair rise, it is important to keep in mind that you should take measurements from the lowest floor to the top floor. The height of stair rise will be different from the height of the room, so make sure you make allowances for floor joists in the room where you are building it. Once you have all of the information, you are ready to build your indoor stairs. You can start building stairs in no time.

Adding a handrail

If you’re adding a handrail to indoor stairs, you’ll need brackets. These must be mounted at each wall stud. In very old homes, with solid brick exterior walls, you may need four brackets. You’ll also need a drill and a miter saw. After you’ve drilled pilot holes, set the rail on the brackets to mark the locations for the screw holes.

The length of your stair railing is important. You must measure the distance between each step and the railing to make sure it’s the correct length. If you’re unsure of the length of your stair railing, measure the distance between each riser. In general, you should have a minimum of four inches between each step. In some cases, you can add a break if the stair is changing directions. To prevent this, include a transitional handrail at each step where there’s a break.

The cost of an indoor handrail varies from $100 to $150 per straight run, depending on its style. Many areas require that handrails have returns at the ends of the stairs, which turn into supporting posts or walls. Each return can cost anywhere from $25 to 50 dollars, and the labor may run up to $500 for a simple flight of stairs. However, this cost is well worth it if your indoor stairs are safe and secure.

The distance between the wall and the handrail must be at least one and a half inches wide. A railing that projects more than one inch from the wall may crowd the walk way. You should also consider the distance between the wall and the closest part of the handrail. This is called the minimum hand clearance. You should keep these measurements in mind when you’re planning a handrail for indoor stairs. In addition, the handrail should be installed between 34 inches and 38 inches above the nosing of the stair treads.


Unless the interior and exterior sides of the stairway are identical, the landing cannot be larger than eight 1/4 inches above the threshold. Similarly, the width of the landing cannot be less than the width of the door served. The minimum dimension of the landing should be large enough for the door to swing over it. These are just a few of the limitations of indoor stairs. Listed below are the other important considerations. Read on to learn more.

The minimum height of indoor stairs is six feet eight inches (2036 mm). The minimum height is measured vertically from the sloped plane adjoining the tread nosing to the floor surface of the landing. The maximum riser height is eight and one-fourth inches (210) and may not exceed three-eights of an inch. In addition, the stairway may be a combination of both curved and straight staircases.
