Choose the calculator for the job
Use Picture Hanging for frame gaps and wall center marks, Board & Batten for repeated decorative wall spacing, and Curtain Fabric when you need fabric widths and total metres or yards.
For outdoor projects, Fence Post Spacing divides a straight run into equal sections below your chosen maximum, while French Drain Gravel estimates the aggregate volume inside a trench. Each tool asks for the measurements that affect that specific job instead of hiding assumptions in a generic construction calculator.
