First release. Twenty-one carpentry calculators and three reference tables, with imperial and metric input, diagrams, and optional text or PDF export.

Description

From the listing uploaded by “catappult”.

Carpentry Trim Calculators is a field guide for roofs, framing, stairs, lumber, plywood, and finish trim. Plan a deck, a wall with openings, hip, gable, and skillion roofs, shelf spacing, kerf bending, and a fence. Work out board and batten, board feet, stud framing, lumber weight, plywood sheets, rafter length, cabinet doors, trim, crown molding, wood movement, stair layout, baluster spacing, and wainscoting. Three reference tables cover lumber sizes, plywood weight, and plywood dimensions. Enter sizes in imperial or metric, then tap Calculate. Diagrams are included on the planners that need them. Results can be shared as text or saved as a PDF. Every calculator is open from the start. You can run 20 successful calculations for free. A failed calculation does not use one of those. Full Version is a single one-time purchase: unlimited calculations, plus share and PDF. It is not a subscription. These tools help you estimate and lay out work. Check critical sizes on site and against your local building code.
