Formula

new = original × (target ÷ original servings)

Linear scaling multiplies every ingredient by the ratio of desired to original servings. Leavening and spice may need slight tuning at extremes.

Worked example

200 g flour for 4 servings becomes 300 g for 6 — scale factor 1.5.

Where this can give the wrong answer

  • Does not auto-adjust baking time — oven time often stays similar.
  • Salt and chili may need less than linear scaling.
  • Round awkward amounts (0.37 egg) sensibly in practice.

FAQ

Mostly yes for moderate changes; very large batches sometimes need slightly less leavening per unit.
