Home & DIY Project Studio

How it works

Typical flow: measure the surface or volume → run the calculator for that work type → add a waste percent → round up to purchase units (cans, boxes, bags, boards) → set unit prices for a budget → collect lines into a shopping list → print or save for the store.

You can keep multiple areas in one project (for example living-room paint plus hallway flooring) so the shopping list and budget stay together.

DIY calculator types overview

Each area has a work type with inputs matched to that job: coverage per liter for paint, box coverage for flooring, tile size and grout for tile, roll size for wallpaper, volume for concrete and gravel, and board counts for wood and lumber.

Switch units between metric and imperial as needed. Results stay estimates — always check manufacturer coverage charts and local product packaging before you buy.

Paint calculator

Enter wall or ceiling area (with optional openings for doors and windows), number of coats, and coverage per liter or gallon. The studio estimates paint volume, can counts after waste, optional primer, surplus, and material cost.

Useful for room refreshes, accent walls, and multi-room paint projects where you want one shopping list of cans and primers.

Flooring calculator

Input floor area and coverage per box (or pack). Apply a waste percent for cuts and pattern matching, then see how many boxes to buy and an estimated materials cost.

Works for laminate, vinyl plank, engineered wood, and similar boxed flooring sold by coverage area.

Tile calculator

Set surface area, individual tile width and height, and grout joint width. The calculator estimates tile count with waste, helping you avoid under-ordering on bathrooms, kitchens, and floors.

Grout and thinset volumes are planning aids — verify bag yields on the product label for your substrate and joint size.

Wallpaper calculator

Use wall dimensions, roll width and length, and pattern-repeat allowances to estimate how many rolls you need after waste.

Pattern matching and drop patterns often increase waste — adjust the waste percent to match the manufacturer’s guidance for your design.

Concrete calculator

Enter length, width, and depth (or volume) for slabs, pads, and footings. Convert to cubic meters or cubic yards and estimate bag counts from bag volume.

This is a quantity estimate only. Structural thickness, reinforcement, and mix design must follow local codes and a qualified professional’s advice.

Gravel calculator

Plan driveways, paths, and landscaping beds by volume. Apply density or bag size assumptions to estimate how many bags or bulk loads to order.

Compaction and base layers change real-world needs — treat results as a starting point and confirm with your supplier.

Wood and lumber

Estimate boards and lumber for decks, fences, shelving, and framing-style cut lists by counting pieces and lengths, then folding waste into purchase quantities.

Lumber grades, spans, and load-bearing rules are outside this tool. For structural or load-bearing work, consult a licensed professional and follow building codes.

Project planning across multiple areas

Group several spaces and work types in one DIY project: paint the bedroom, tile the bath, and gravel the path without losing track of totals.

A shared budget and shopping list make multi-room renovations easier to plan before you visit the home center.

Shopping list and print

Purchase-unit lines (cans, boxes, bags, boards) roll into a shopping list you can review, adjust, and print for the store.

Pair material lines with optional tools and consumables so you leave with everything for the weekend project.

Privacy: zero upload, localStorage only
