Reference & details

How it works

Component Weight Breakdown

Total hive weight = equipment (boxes, frames, foundation) + bees + honey/pollen stores. A deep box empty weighs ~40 lb; medium ~30 lb.

Total = box weight + (frames × content weight) + bee mass

Honey Weight per Frame

A fully capped deep frame holds ~8 lb honey; medium frame ~6 lb. Partial frames estimated by capped percentage.

Honey (lb) = Σ (frames × fill% × frame capacity)

Winter Readiness Benchmark

Northern climates need 60–90 lb total hive weight going into winter (including bees and equipment). Southern climates may need 30–50 lb stores.

Required stores (lb) = colony size × regional winter factor

Updated: July 2026

Example Scenarios

2 deep boxes + lid/bottom (~90 lb equipment/bees) + 12 capped deep frames (~96 lb honey): total ~186 lb. Adequate for northern winter if varroa controlled.

Hive weighs 145 lb on May 1, 158 lb on May 15: 13 lb gain in 2 weeks during nectar flow — roughly 1 lb/day, indicating strong foraging.

Rear of hive hard to lift = adequate stores. If rear lifts easily in October in cold climate, colony likely needs emergency feed before winter.

Common Mistakes to Avoid

Estimating stores by frame count without checking capped percentage

Partially filled frames may look full but contain nectar (high moisture) not cured honey. Only capped honey counts as reliable winter stores.

Using summer hive weight benchmarks for winter assessment

Summer hives include brood, bees, and empty comb weight. Fall/winter assessment focuses on capped honey stores above the cluster, not total summer weight.

FAQ

Varies by region: northern US/Canada 150–200 lb total (60–90 lb honey stores). Mid-latitude 120–160 lb. Weigh or heft-test in fall before cold weather.

Fully capped deep frame: ~8 lb honey. Medium frame: ~6 lb. Shallow super frame: ~4 lb. Use capped percentage to estimate partial frames.

Yes — tilt hive from rear and hook scale under back edge, multiply reading by approximate lever ratio, or use platform scales under hive for accurate total weight.

A strong summer colony: 3–5 lb of bees (~30,000–60,000 workers). Winter cluster is smaller. Bee mass is included in total hive weight benchmarks.

Rapid weight loss in summer may mean swarming (bees departed) or robbing. In winter, gradual decrease is normal cluster metabolism — sudden drop suggests starvation or colony loss.
