Plan a DIY project with a step list and materials list

Describe the project and measurements and get the steps, a shopping list with quantities, and a realistic timeline.

The problem

Weekend projects like painting a room, building raised garden beds, installing a backsplash or replacing a faucet usually take three trips to the hardware store because something was forgotten. Measuring and estimating quantities is where most DIY plans fall apart.

Step by step

1. 1Measure the space (length, width, height; number of doors and windows for paint) and take a photo or two.
2. 2Open ChatGPT, Claude or Gemini and paste the prompt below with the project, measurements and your skill level.
3. 3Check the quantities against the product labels: coverage per gallon of paint, square feet per box of tile, and so on. Add about 10% extra for cuts and mistakes.
4. 4Paste the materials list into Google Sheets or your phone notes, and check prices on a home improvement store's website or app before you go.
5. 5Follow the step list, and stop to look up a trusted how-to video for any step you've never done.

Copy-paste prompt

Help me plan a DIY project: [project]. Measurements: [details]. My skill level: [beginner/some experience]. Tools I already have: [list]. Budget: $[amount]. Give me: (1) a step-by-step plan in order, with time estimates and drying/curing times; (2) a materials list with quantities, showing your math (e.g., wall area ÷ coverage per gallon) and adding about 10% extra; (3) tools I need to buy or rent; (4) safety gear and any step where I should consider hiring a pro; (5) the most common beginner mistakes for this project. Mark prices as rough estimates.

Tips and watch-outs

• Wear eye protection and the right gear for the job (gloves, dust mask, hearing protection).
• Call 811 before you dig, so buried utility lines get marked for free.
• Electrical circuits, gas lines, load-bearing walls and roofs need a licensed pro and often a permit; check with your city or county.
