About Tape & Tally

Tape & Tally is a small collection of home-improvement calculators built around one idea: measure once, then buy the right amount. No sign-ups, no fluff — type your room size, get the number of boxes, bags or gallons to buy, with a sensible waste allowance and a rough materials cost you can edit.

What makes these different

• Real package sizes. We round up to whole boxes and bags the way a store actually sells them.
• Waste built in. Every calculator adds a realistic waste allowance you can adjust.
• Fast on a phone. The calculator loads first and works before anything else does.
• Honest costs. Prices are shown as rough, editable estimates — never quotes.

Who it's for

DIYers and homeowners planning a project — a bathroom re-tile, a room repaint, a new floor — who just want a trustworthy number before a trip to the store.
