Start with the room and the selected tile.

The product’s size, selling unit and pack coverage determine the calculation. Keep those details visible with the measurement.

Choose the quantity mode your product supports.

Convert measurement units, deduct excluded areas, add the chosen extra allowance and then apply the mode’s rounding. Loose-piece selling has separate product prerequisites.

Quantity modes and their product prerequisites
Mode	Before using it	What the result means
Area to whole boxes	Positive saved coverage per box and a supported coverage unit.	The required area is divided by coverage and rounded up to whole boxes.
Piece-tracked product	A current package definition, positive pieces per box and valid area coverage.	The calculation uses the saved pack relationship; a room measurement does not create that setup.
Loose pieces or boxes + pieces	Piece tracking plus loose-piece selling enabled for that product.	The allowed loose or mixed quantity. Otherwise choose Whole boxes.
I know the quantity	A known quantity in the product’s allowed boxes/pieces or native unit.	Direct entry, without an area or extra-allowance calculation.

Missing pack data should stop the guesswork.

Keep the measurements while correcting a prerequisite. When the quantity is already known, use the explicit direct-quantity mode in the product’s actual unit.

When a required detail is missing

Missing coverage: Choose “I know the quantity” and enter the eligible boxes or pieces directly, or correct the saved coverage.
Loose pieces unavailable: Choose “Whole boxes” under “Order as”; a room measurement does not enable piece selling.
Invalid or excluded area: Use positive dimensions and deductions smaller than the measured area.
Changed product or override: Reopen the calculator when the product changes. Keep a reason with any manual change to its recommendation.

Carry the reviewed quantity into the sale.

Apply the result to the editable sales form, then check the product, unit, quantity and rate together before saving.
