Estimate bushels per acre for corn, soybeans, wheat, canola, dry beans, and other row crops. Enter plant population, ear or pod count, and kernel or seed weight — the calculator handles the rest in both Imperial and metric units.
Calculate bushel capacity for grain trailers, grain carts, and semi hopper trucks. Select a common preset or enter your own dimensions — get total bushels, weight in pounds and tons, and how many loads it takes to haul a given field. Useful for harvest planning, trucking logistics, and elevator scheduling.
Estimate harvest and revenue for up to 5 crops. See individual results and a whole-farm summary.

Grain cart capacity varies widely by size. A small 500-bushel cart has interior dimensions of roughly 8.5×6×5 ft. A large 1,300-bushel cart is approximately 12×7.5×6 ft. Capacity is calculated from interior volume divided by the standard cubic feet per bushel (1.2445 cu ft/bu for a 56-lb bushel of corn). Use the preset selector to quickly estimate common cart sizes.
A standard semi hopper grain trailer holds approximately 900–1,000 bushels of corn depending on interior dimensions. Common dimensions are 40–42 feet long, 8 feet wide, with a grain depth of 4.5–5 feet. Legal gross vehicle weight limits (80,000 lbs in the US) may limit actual load size before volumetric capacity is reached — always verify against scale weights for commercial loads.
One standard US bushel equals 2,150.42 cubic inches or 1.2445 cubic feet (the Winchester bushel). To convert cubic feet to bushels, divide by 1.2445. Actual weight per bushel varies by grain — corn is 56 lbs/bu, soybeans and wheat are 60 lbs/bu, canola is 50 lbs/bu.
Divide total field bushels by cart capacity. For a 200-acre field at 200 bu/acre (40,000 total) with a 1,000-bushel cart, you need 40 loads. Enter your total field bushels in the Haul Planning section and the calculator does this automatically, including the last partial load and total haul weight.
This is a general-purpose grain container capacity calculator that works for any rectangular or near-rectangular grain container — grain carts, hopper-bottom trailers, semi grain trucks, and flat-bottom wagons. It is not specific to any brand or manufacturer. Select a preset for a quick estimate or enter your exact interior dimensions for a precise calculation.
