Measure twice, buy once

Rough math before the hardware-store run.

Paint gallons. Flooring boxes. Mulch bags. Concrete mix. Gravel tons. Put in the measurements you actually have and get a number you can take to the aisle.

SHOP NOTE

Most mistakes happen before checkout.

Coming up short by one box or buying six extra bags both hurt. These calculators are built for the messy middle: quick enough for a Saturday morning, clear enough to double-check.

Pick the job on your list

Five calculators that solve common weekend-project guesses.

Each one shows the raw estimate, a rounded buy quantity, and the assumptions behind it so you can change the numbers instead of trusting a black box.

Painting

Paint Calculator

Estimate how many gallons of paint to buy based on room size, wall height, doors, windows, coats, coverage, waste, and price.

Open calculator

Landscaping

Mulch Calculator

Estimate how much mulch you need for beds and landscape areas using length, width, depth, bag size, and price.

Open calculator

Built around store reality

Materials come in gallons, boxes, bags, and tons. Results round up the same way.

Defaults you can argue with

Coverage, waste, depth, and bag yield are editable because products and projects vary.

Plain-language formulas

No contractor theater. Just measurements, conversions, and enough context to catch a bad input.

WHY THIS EXISTS

For people standing in the garage with a tape measure.

Count Before You Cut is for homeowners, renters, and weekend fixers who need a planning number before they drive to the store. It is not a contractor, an inspector, or a code book. It is the scratch-pad math you do before spending money.
