Stile Calculator: How To Calculate Stiles And Rails?

The stile is the distance between two pieces of lumber or other material. For example, if you have a piece of plywood and you want to make it into a table top, then you need to know how much stiles are required. If you want to build a table with plywood, then you will need to know how many stiles are needed.

In order to determine the number of stiles required, you need to know the width of your board. Then you can use this measurement when calculating the length of your boards. So, let’s say that your board measures 1 inch (2 cm). You would need 4 inches (10 cm) of stiles.

Now, what if your board measures 2 inches (5 cm)? You would need 8 inches (20 cm) of stiles.

What about 3 inches (7 cm)? You would need 12 inches (30 cm) of stiles.

4 inches? Well, you’d probably need 16 feet (50 m) of stiles! That’s a lot! You would need to cut one stile for each inch (2 cm) of width.

Now, let’s say that your board measures 2 inches (5 cm). You would need to cut two stiles for each inch (2 cm) of width.

And so on…

It is very simple to calculate the number of stiles required based upon the dimensions of your boards. However, there are times when you may not have all the measurements available at hand.

The width of your board is the most important factor in your stile measurement. If you are building a long table, it may be difficult to achieve the right look if you do not use enough stiles. The table will look unbalanced, and this may cause problems in design.


Rails are the horizontal pieces at the bottom of a door or window. You may need to know how to calculate stiles and rails without all the measurements at hand.

Here’s a quick guideline on how you can do it:

1. Work out your stile length based upon the width of your board. 2. Now, take that number and double it. 3.

Add 5 inches (12.5 cm) to that number. This is the total length of your rail. 4. They serve to join all the vertical pieces together. These horizontal pieces are often shorter than the vertical boards, but there is no rule that says this has to be the case.

You can use different types of materials for rails, such as plywood or hardwood. The choice will depend upon the door or window you are building and the design you wish to achieve. For example, if you are making a half-door for your basement, then you may only need a short rail. Cut your rails to size.

Let’s say that you want to make a door with a 1-inch (2 cm) thick plywood board. Let’s also say that the width of your board is 30 inches (75 cm).

To work out the number of stiles required, you would multiple the width of your board by 2. Sticking with our example, that would mean 60 inches (150 cm). That seems like a lot of stiles! However, if you are making a door for the entrance of your home, then a long narrow piece of hardwood may be more suitable. Let’s take a look at the other measurements.

To work out the length of your rails, you would multiple the number of stiles by 5. In our example, that would be 300 inches (750 cm). Let’s add 12.5 cm to that measurement for each side, which would give us a total rail length of 337.5cm.

We can cut this to size when we come to it.

Let’s get back to the stiles. As we said, you would need 60 inches (150 cm) of stile for our example. Take your wood and mark two lines across it at 60 and at 150 cm. Then, place a line between these two points. This is your stile.

You may want to sand it down to make it smooth and even.

Make as many stiles as you need or as you can afford.

If you are making a door with more than one panel, you can use half-stiles at the middle of your door. These are one-half the width of a regular one. If you are making a bi-fold door, then you may want to make your stiles only 30-inches (75 cm) long. This will give the door more folds and make it look more impressive.

To work out the size of your rails, take your stiles one at a time and measure the gap between them. Let’s say your stiles are 50 cm wide. You will add twice the width of each stile to get the gap between them. That would make it 100cm. Now, take that number and divide it by 2, since you only need enough rail to cover half of that distance.

In our case it would be 50 cm. The length of each rail is then equal to the length of your stile. In other words, if each of your stiles is 1 meter long, then each rail should be 500 cm long (or whatever length you wish your door to be).

Make as many rails as you need or can afford. You may need different types of wood for these. If you’re using hardwood for the stiles, then using softwood for the rails is a good idea (and vice versa).

After you have cut your rails to size, it’s time to start building the frame.

Making the Door Frame

The first step in making the door frame is to lay out the stiles. Place two of them together at the bottom and place a rail on top of each side. Make sure that the corners are right angles. If not, then adjust them until they are. If you need to, use wood scraps to fill in any gaps.

Now, place a rail on top of the other two stiles and adjust the corners until they meet at a right angle. Use wood scraps to fill any gaps as before.

That’s it for the basic frame!

Making the Door

The door is made from plywood, hardwood, or in some cases hardboard or softwood planks. Your choice of door will be determined by a number of factors such as cost, availability, weather conditions, and personal preference.

Making the Door

Start by cutting your plywood or hardwood planks to size. Narrower doors are easier to get in and out of, not to mention they are more energy efficient. A good width is about 60 inches (150 cm) for most applications. The height can vary from 86 to 96 cm (adjust for your own height).

Next, take the door stiles and place them on a flat surface. Lay the plywood sheet on top of two of the stiles and trace their outline. Cut out the outline using a jigsaw or bandsaw (Or have it done by someone who is better at using the tool).

Do this for each plywood sheet. When finished, you should have four door panels.

Now lay out the door frame on a flat surface such as a floor or table. Place the door panels into the frame, making sure that all the edges are a little bit within the frame. The space between the door and frame (known as the reveal) should be about 3 cm all the way around. Adjust the panels if necessary.

Finally, place the inside trim on each door panel. This can be done in a number of ways. One way is to cut it into narrow strips and simply nail it into place. Another is to use quarter-round moulding and to simply glue it around the panel. A third way (which I prefer) is to use stick-on cove moulding.

This gives the door a professional look.

After the panels are complete, fill in the space between the inside trim and the frame using wood filler. Let it dry, then sand the filler and the entire door down before painting with primer and paint.

Optional: Hinges, Latch, and Pull

If you painted the door, it’s best to stain the wood before assembling. Stain all the interior parts of the door (that is, everything but the panels). Then assemble everything except for the hinges and latch.

Open the door by hand a few times to make sure that it isn’t too difficult to move. If it is, then apply more stain to the hinges and latch.

Stain or paint the hinges and latch and attach them to the door. If you want, you can also attach a pull to the edge of one of the panels.

Finally, you’re ready to install your new door.

Installing Your Door

Most interior doors are held in place with three hinges. These are usually located on the edge of the door that doesn’t have a knob. The hinges are mounted to wooden strips (called the hinge rail) which are attached to the door frame. The strips may be attached to the frame already or you may have to predrill screw holes and secure them with screws or nails.

The door latch is held in place by screws or nails. When installed, it locks the door in place and keeps it from being opened. The way it works is by pressing the top of the latch up (with the handle) and lifting up at the same time.

To test if your door opens and closes without difficulty, take off the hinges and latch. Open and close it by hand a few times. If it moves smoothly, then put the hinges and latch back on. If not, you may have to sand or plane down the edges inside the door frame (the part that touches the edge of the door). Doing this also makes the door easier to open and close.

The last thing to do is to prime and paint the door, if you haven’t already done so.

Concluding Words

Making a door isn’t too hard of a project if you’re patient and follow the instructions properly. You’ll also need to take critical thinking into account when choosing the style of door and designing it.

Making the door is just half the battle, though. Next you’ll have to learn about installing locks and entry phones for maximum security.

Good luck!
