Quickly calculate equal spacing, position marks, margins, and material thickness for woodworking, DIY, metalwork, welding prep, and layout work.
Equal Spacing Calculator is a simple layout tool for anyone who needs to place marks at equal intervals quickly and accurately.
Enter the total length, number of divisions, and left/right margins to calculate the spacing and a full list of positions measured from the edge.
You can also account for material thickness or width, choose the reference side, and check the result with a simple visual guide. Because values can be adjusted and re-checked instantly, it works well both during planning and on-site layout work.
