Decks, Fences & Roofing
Framing and exterior structures by the board, panel or square.
Fence
Posts & pickets
Estimate wood fence posts, rails, pickets and concrete from total length, height and post spacing — pick a privacy, picket or shadowbox style, with gates and waste.
Chain Link
Pet & security fence
Estimate chain-link fence materials — terminal and line posts, top rail, mesh fabric, tension bands, caps, ties and concrete — from total length, height, corners and gates.
Roof Pitch
Pitch, angle & slope
Convert roof rise and run into pitch (x-in-12), the roof angle in degrees, grade percentage and the slope multiplier, plus rafter length.
Rafter Length
Common rafter & cuts
Calculate common rafter length from your roof span and pitch — line length, overhang, total board length, the plumb and seat cut angles, the birdsmouth depth, and how many rafters to buy.
Roofing
Shingles & squares
Calculate roofing materials from your roof's footprint and pitch — shingle bundles, squares, underlayment, drip edge, starter, ridge cap and nails.
Siding
Squares, boxes & cost
Calculate how much siding you need in squares, plus the boxes, planks or panels to order — from your wall perimeter, height, gables and openings. Works for vinyl, fiber cement, wood lap and board & batten.
Stairs
Rise, run & stringers
Calculate stair risers, riser height, tread depth, total run, stringer length and the slope angle from your total rise — to code.
Deck
Boards, joists & screws
Calculate the decking boards, joists and screws for a deck from its length and width, with board size, joist spacing and a waste allowance.
Wall Framing
Studs & plates
Calculate how many studs and how much plate lumber a wall needs — from its length, height and stud spacing — including extra studs for doors, windows and corners, plus the total 2×4s to buy.

The formulas, conversions and how-tos behind these calculators.
How Much Concrete Do You Need Per Fence Post?
Plan for 1–2 bags of 50 lb fast-setting concrete per fence post, depending on hole size.
How Much Does a Fence Cost? (Per Foot, by Material)
A fence costs about $15–$60 per linear foot installed, depending on material. Wood runs $15–$45/ft, vinyl $25–$60, chain link $10–$25. Full price breakdown.
Vinyl Fence Cost (Per Foot & Installed, 2026)
Vinyl fencing costs about $25–$60 per linear foot installed — roughly $15–$30/ft in materials plus labor. Cost by style, height, and DIY vs. pro.
Standard Fence Height (and Local Height Limits)
Backyard fences are typically 6 ft and front-yard fences 3–4 ft. Most cities cap front fences at 4 ft and back/side at 6–8 ft. Check setback and code rules first.
How Many Fence Pickets Do I Need?
Pickets = fence length in inches ÷ (picket width + gap). A 100 ft solid fence of 5.5 in pickets needs ~218 boards. Board-on-board needs roughly double.
Fence Post Spacing (How Far Apart, Depth & Size)
Space fence posts 6–8 ft apart on center. Set them at least one-third of their length deep and below the frost line. Posts = sections + 1, plus gate and corner posts.

How to Measure Roof Pitch (3 Easy Methods)
Measure roof pitch with a level and tape, from inside the attic on a rafter, or from a photo. Here's how to find the rise-over-12 and convert it to degrees.

How Long Does a Roof Last?
An asphalt-shingle roof lasts 15–30 years; metal 40–70; tile and slate 50+. A lifespan chart by roofing material, plus what shortens it.
How Many Shingles Do I Need? (Bundles & Squares)
Roofers buy shingles by the square (100 ft²) and the bundle (1/3 square). Divide roof area by 100 for squares, then ×3 for bundles, + 10–15% waste. Chart by roof size.
How Much Does a New Roof Cost?
A new asphalt-shingle roof costs about $5,500–$16,000 installed, or $450–$750 per roofing square. A cost breakdown by material and roof size.
How Much Does a Metal Roof Cost?
A metal roof costs about $8–$16 per square foot installed — roughly $12,000–$24,000 for a typical 1,500 ft² roof. A cost breakdown by panel type.

Standard Stair Dimensions (Rise, Run & Code)
Standard stairs use a 7–7.75 in riser and a 10–11 in tread. Here are the IRC rise and run limits, headroom, width and the 2R+T comfort rule.
How to Calculate & Cut Stair Stringers
Lay out a stair stringer with a framing square: mark the rise and run for each step, account for the first-riser drop, and cut from a 2x12. Step-by-step.
How Many Deck Boards Do I Need?
Count deck boards: rows = width ÷ (board + gap), then × length for linear feet, + 10% waste, ÷ board length. Includes a boards-per-deck chart.
Deck Joist Spacing (12, 16 or 24 Inches?)
Deck joist spacing explained: 16 in on center is standard, 12 in for diagonal or stiffer decks, 24 in only with rated composite. Span and o.c. basics.
