  • It gives a repeatable method for multiple rooms.
  • It is faster than manual tape-measure math.

Frequently Asked Questions

Is PaintPlanner a paint calculator or just a room scanner?

PaintPlanner is both. It uses room scanning to measure paintable area and then calculates estimated paint quantity based on your selected coverage and coats.

How much paint do I need for a room?

That depends on wall area, openings, paint coverage, and number of coats. PaintPlanner calculates this automatically after a room scan, so you can get a practical estimate in minutes.

Does the app account for doors and windows?

Yes. PaintPlanner subtracts doors, windows, and other openings to improve estimate accuracy.

Can I plan multiple painting projects?

Yes. You can save estimates and compare rooms so you can plan full interior painting jobs more easily.

Is this useful for homeowners and pros?

Yes. Homeowners can avoid guesswork when buying paint, and professionals can create faster and more consistent estimates.

Do I need a specific iPhone?

For room scanning, you need a LiDAR-capable iPhone model. The app listing in the App Store has the latest compatibility details.

Paint Estimate Tips

  • Use the paint can coverage rate recommended by the manufacturer.
  • Set realistic coat counts (for example, one coat for refresh, two for color changes).
  • Re-scan unusually shaped rooms for better geometry.
  • Compare estimate results before purchase.
