Stagecraft Calculators & Tools
Free, practical tools for community and amateur theatre — check your sightlines, plan rehearsal time, match your lighting gels, budget your props, time your script, and grid your stage for blocking.
Sightline & Riser Calculator
Work out how much each row of raked or platformed seating needs to step up so every seat clears the head of the row in front — a full riser table, row by row
Rehearsal Scheduler
Split the rehearsal hours you actually have across your scenes, in proportion to how much stage time each one needs, with a reserved block for tech and dress
Lighting Gel Color Temperature Calculator
Get the mired shift between two color temperatures and a suggested CTO or CTB correction strength, so mixed fixtures match under the wash
Prop Budget Planner
Add up your prop list with a contingency built in, and see how the total compares to your production budget before tech week arrives
Script Runtime Timer
Estimate how long a script runs on stage from its page count, using the page-a-minute rule, with pace, intermission, and per-act adjustments
Blocking Grid Generator
Turn your stage's width and depth into a labelled grid of numbered squares to print and mark blocking notes onto
