Depth, spacing, gravel and curing
Fence Post Installation Guide is a free guide from Smart Fencing Calculator. Set wood, vinyl and metal fence posts in concrete the right way: correct depth, spacing, gravel base, mix ratios and curing time for posts that will not lean. This guide is built for homeowners, DIYers and fencing contractors who want fast, accurate fence estimates without signing up or installing anything. Enter your fence dimensions, choose your material, and the tool returns the materials list, quantities and indicative project cost in seconds. Every result is rounded with a sensible waste factor so you can take the numbers straight to a lumberyard or supplier. Use it alongside our other free fence calculators for posts, pickets, rails, concrete, gates, stain and total project cost. If you are pricing a full project, start with the linear footage calculator, then layer in posts, pickets and concrete to build a complete bill of materials.
