The measuring bench

Garden calculators that show their work.

Use a worksheet, read the assumptions, print the result, and keep the site-specific judgment in your hands.

Build the fill list

Turn bed dimensions into cubic feet, cubic yards, liters, and a realistic bag count—with settling reserve included.

Cover, without overbuying

Estimate mulch by area and finished depth, then translate the answer into yards, liters, or bags.

See the bed before sowing

Compare straight-grid and offset layouts, estimate plant count, and preview every planting point.

Fill pots by geometry

Estimate mix for round or rectangular containers, multiply a whole set, and convert to common bag sizes.

Size storage from the roof

Translate roof area and a design storm into collectable gallons or liters with a user-set efficiency factor.

Work backward from frost

Choose a crop and your local last-frost date to create an indoor sowing and transplant window.

Turn flow into minutes

Balance bed area, a chosen weekly water depth, emitter flow, and watering frequency to estimate runtime.
