Enter fractions as decimals. Number of Rails. It is recommended that you use a minimum of 2 horizontal rails between posts for all fences less than 5' high, 3 rails for fences 5' to 7' high, and 4 rails for 8' high fences. Fences taller than 8' are outside the scope of this calculator due to structural considerations. A line of fence is defined as a continuous stretch of fence unbroken by corner posts, gates or other breaks in the fence line. Use feet and fractions of a foot expressed as a decimal.
You could have a single line of fence of say feet with a gate exactly in the center of that line. If the gate is to be 4' wide, that leaves 96' of fence, not counting the gate.
The gate divides that 96' in half, so you would enter these figures: Stretch 1 is 48', stretch 2 is 48' and then enter the gate in the gate field. To enter that stretch of fence as ' or even 96' in one field would be incorrect. The calculator would assume the gate goes on the end and could not compute the proper spacing of posts. Curving Fence Lines: An oddity would be if you intended to curve your fence using the post spacing you have chosen to change the angle off a true straight line.
Using this 'curving' technique, it is possible to create a complete circle eventually, whereby you do not technically have a corner post. In this case, since you will be using full post spacing, enter the entire curved line as one field entry. Calculating curves with post spacing less than the amount you enter as your post spacing choice, is outside the scope of this calculator, since the program will only use one post space entry for calculations.
Single Swing Gate. A single swing gate is a gate that uses hinges and only has one leaf. How much material you need to build your fence depends on the style you want. The first step in figuring out how much wood is needed to build a fence is to measure the length. Given the total length, you can estimate the number of posts you need. Posts are typically 8 feet apart. Then, add 1 to account for the last post.
To calculate rails, decide the number of rails you want. This will vary by the style and height of the fence, but there should be at least two. Multiply the number of sections by the number of rails per section to find the total rails needed. The number of sections can be found by subtracting 1 from the number of posts in the previous step. There will be two rails per section.
To calculate pickets, decide the width and spacing of your pickets. Add the width and the spacing together to get the combined width. Change the length of your fence to inches to match the picket measurements. Divide the fence length by the total picket width to get the number of pickets needed. Plan on ordering lumber to build gates as needed, including additional posts and hardware. Wood is often chosen for its durability, aesthetics, and affordability.
To determine a solid price estimate, decide on the fence style and type of wood you want and accurately estimate the amount of material needed. Common wood choices are pressure-treated wood, cedar, or redwood, and they vary in price considerably. It is important to have a gap here to prevent premature rot of the pickets.
Next, decide how to attach your fence rails to the fence posts. They can either be face nailed to the posts or toe nailed. A diagram of rails that are toe-nailed can be seen above. Here is what a face nailed wood fence looks like:. Instead of walking the perimeter of your fence line with a measuring tape, use the Google Maps Distance Tool to view your property in satellite mode and trace the part of the fence you want to replace or install. The map will provide a rough estimate of your lineal footage.
This option is especially useful for large properties. Determine if you want a short fence — which has a height of approximately 3 feet —or a tall fence, which can range from 3 to approximately 8 feet. Short fences require less material while tall fences create more privacy. Determine the number of gate openings your fence will need. The number of gates will have an impact on the number of posts in your materials order.
Pre-fabricated gates are a fantastic way to include a professionally-crafted focal point without having to hire a contractor. Make a rough sketch on a piece of paper of the shape of your yard.
The main thing is to include the number of corners or any unusual angles and write down lengths of each fence section. Are any areas of your yard higher or lower than the rest?
