AHAM sizing. Garage reality.

Capacity baseline derived from AHAM household-freezer guidance; operating-range thresholds from ENERGY STAR garage-ready specifications and standard freezer manufacturer documentation.

  1. 01

    Capacity baseline

    Min = 5 + (people × 2). Max = 8 + (people × 3). A 4-person household lands at roughly 13–20 cu ft for general use.

  2. 02

    Use-case multiplier

    Meal prep ×1.3–1.5. Bulk buying ×1.5–1.8. Hunting / game storage ×2–2.5. These dominate the sizing decision.

  3. 03

    Garage-rated check

    Standard freezers operate 55–90°F. If your garage drops below 32°F or hits above 100°F, you need a garage-rated unit (0–110°F operating range).
