Board and Batten Calculator
A board and batten wall looks balanced when the spaces between the vertical boards are equal. This layout calculator works from the finished wall width, actual batten face width, and the largest clear gap you want. It places a batten at both ends, finds the smallest number of equal bays that meets your gap target, and reports the material length.
Wood, Deck & FenceBoard Foot Calculator
Board feet measure wood volume rather than the length of a board or the area it covers. This calculator helps compare a rough-lumber quote with the stock needed for a woodworking project. Enter the thickness and width used by your supplier for billing, then enter the length and number of equal boards.
Wood, Deck & FenceLumber Cost Calculator
A linear-foot estimate can understate the bill when lumber is sold only in whole stock lengths. This calculator converts your required finished length and cutting allowance into a purchase count, then applies the actual price per stock board. It separates material, tax, and delivery so you can compare local supply options.
Wood, Deck & FenceDeck Board Calculator
Decking is easier to estimate when you count rows and the pieces needed in each row rather than dividing the deck area by a nominal board size. This calculator uses the width across the board rows, the run length along each row, the actual face width, and the intended gap.
Wood, Deck & FenceDeck Screw Calculator
Deck screw quantities depend on the number of board-to-joist intersections, not just the deck area. Enter the actual count of decking rows and supporting joist lines, along with the number of screws required at each crossing by the board installation instructions.
Wood, Deck & FenceDeck Stain Calculator
Deck staining often includes more than the flat deck footprint. This calculator combines the walking surface with a separately measured area for railings, risers, treads, and exposed trim. Enter the stain label’s coverage per gallon and the number of coats allowed by the product.
Wood, Deck & FenceFence Material Calculator
A panel fence purchase starts with the fence run, but gates and end conditions change the counts. This calculator subtracts a gate opening from a straight run, divides the remaining fence into bays no wider than your chosen limit, and counts the posts and rails for those bays.
Wood, Deck & FenceFence Picket Calculator
Picket count is most accurate when you estimate the clear infill spans rather than the entire property line. This calculator finds how many pickets fit within one repeated bay while maintaining at least the requested clear gap between boards. It reports the adjusted equal gap, multiplies by the number of matching bays and fence faces, and adds a spare allowance.
Wood, Deck & FenceFence Stain Calculator
Fence stain estimates should distinguish a single face from both sides and allow for rails, post edges, and other surfaces outside the flat outline. This calculator starts with fence length times height, multiplies by the number of faces being coated, and adds any separately measured detail area.
Wood, Deck & FenceFence Post Spacing Calculator
Even fence post spacing avoids a short leftover bay at the end of a straight run. This calculator divides the measured distance between end post centers into equal bays that do not exceed your chosen maximum center spacing. It returns the number of bays, number of posts, and a station list measured from the first end post.
Wood, Deck & FenceBaluster Spacing Calculator
A tidy baluster layout shares the available space across the gaps at both ends and between every baluster. Enter the clear distance between the boundary posts, actual baluster width, and your selected maximum clear opening. The calculator finds the smallest baluster count that keeps all equal gaps within that limit and reports the center-to-center pitch.
Wood, Deck & FencePlywood Sheet Calculator
Plywood sheets cover a surface differently depending on which edge runs along the project length. This calculator compares two simple grid orientations and reports the smaller whole-sheet count before applying a separate extra-sheet allowance. It is useful for planning a rectangular sheathing or lining surface where offcuts are not redistributed between grid positions.
Wood, Deck & FenceWall Stud Quantity Calculator
A wall lumber takeoff needs more than a spacing calculation. This tool counts a simple continuous run of studs, then lets you add the specific extra studs in your framing plan for corners, intersections, and openings. Plate courses are calculated separately and rounded to stock lengths.
Wood, Deck & FenceWood Weight Calculator
Wood weight changes with species, moisture, dimensions, and treatment. This calculator uses a density you supply rather than assigning one universal value to a species name. Enter the actual board thickness, width, length, and quantity to calculate solid wood volume and estimated weight.
Wood, Deck & FenceMiter Angle Calculator
A corner angle and a miter-saw scale reading are different measurements. This calculator finds equal flat miters for two matching pieces that meet at a measured interior corner, or for all corners of a regular polygon. The saw setting is measured away from a square crosscut.
Wood, Deck & FenceShelf Spacing Calculator
Equal shelf spacing must account for the thickness of each shelf as well as the objects you want to store. This calculator shares the available inside height across the openings above, between, and below a chosen number of shelves. Fixed margins let you reserve space for hardware or a raised base.
Wood, Deck & FenceCabinet Door Size Calculator
Cabinet door dimensions depend on the opening style and on the hinge system you intend to use. This calculator handles a single door or a pair of equal doors, in either overlay or inset form. It applies the selected perimeter overlay or inset clearance, then splits paired doors around a center gap.
Wood, Deck & FenceDrawer Box Calculator
Drawer box sizing begins with the clearance required by the actual slide hardware. This calculator subtracts side clearances from the cabinet opening, then produces a simple butt-jointed box cut list with front and back pieces fitted between the full-length sides.
Wood, Deck & FenceWood Movement Calculator
Solid wood changes dimension as moisture content changes, especially across the grain. This calculator estimates that change using the board width, two moisture-content readings, and a coefficient appropriate to the wood and grain orientation. The coefficient is entered per one percentage-point change in moisture content, so its units matter.
Wood, Deck & FenceRepeated Cut List Calculator
Repeated parts are a useful place to reduce waste before buying lumber or trim. This calculator determines how many identical pieces fit in each stock length after a total end-trim allowance and a saw kerf for every part cut. It then reports the stock pieces required and the remaining material.
Wood, Deck & FenceSandpaper Quantity Calculator
Sandpaper consumption varies with finish, wood, pressure, dust extraction, and the point at which you choose to replace an abrasive. This calculator uses your observed or expected usable area per disc or sheet at each grit stage. Enter the number of stages, the project surface area, and an extra-change allowance to plan a purchase.

How to Plan Even Board and Batten Spacing Around Outlets
The difficult part of a board and batten accent wall is usually the layout. Equal spaces look simple in a finished room, but a wall can contain an outlet, a switch, a corner return, and a baseboard that changes the available width.

A useful deck material list separates the visible surface from the supporting structure. Deck boards, surface fasteners, fascia, and finish can be estimated from a detailed layout, while joists, beams, posts, foundations, and connections need their own design and takeoff.

A fence estimate becomes much more reliable when it follows the layout instead of starting with a generic price or material rate per foot. Posts, panels, pickets, rails, and gates each follow a different counting rule. A gate removes infill length but can introduce extra boundary posts and hardware.

Lumber can be priced by the board, by the linear foot, by the board foot, or by a package. Each unit answers a different question. A low number on one quote may be more expensive than a higher number on another if the billing units differ.

A pile of stock can contain enough total length and still fail to produce the required parts. Each cut consumes material, long pieces cannot be assembled from arbitrary scraps, and the last offcut on one board may be too short for the next part.
