Planning a bulk jute, cotton, or canvas bag order requires knowing your shipping footprint. This calculator uses real factory packing data to instantly determine your carton sizes, box volumes, and total capacity for 20ft or 40ft containers. Estimate your logistics before finalizing your custom eco-friendly bag quantities.

How to Use This Calculator

This tool calculates the total quantity of jute, cotton, or canvas bags per export carton and the total number of cartons of jute, cotton, or canvas bags that fit into a 20 or 40 feet container. This free tool can estimate the loading capacity of a 20 or 40 container for jute bags, canvas bags, or cotton bags.

Carton & Container Packing Calculator

Estimate carton size and 20ft / 40ft container loading for jute, cotton and canvas bags.

This is an estimate only. Based on practical internal container space of 80 × 235 × 80 inch for a 20ft container, with cartons per axis rounded to the nearest whole carton. Actual loading can be higher, since our team may flip or reorient some cartons during hands-on loading to maximise space — this calculator gives a planning estimate, not the final loading plan. 40ft capacity shown as double the 20ft estimate. Final carton size is confirmed with our production team before container booking.

FAQ (Freequently Asked Question About Shipping of Jute or cotton bags ):

How do I calculate carton size for export bags?

Carton size is based on the bag’s folded width and length, plus a small allowance for fitting into the carton, and a height calculated from the material’s stacking thickness multiplied by the number of pieces per carton. Different materials compress to different thicknesses, so jute, cotton, and canvas bags of the same size still need different carton heights.

It depends on your bag’s folded size, material, and how many pieces you pack per carton. As a rough guide, a standard 20ft container holds around 280-320 cartons of typical tote or shopping bag dimensions, though this varies significantly with carton size — use the calculator above with your own bag measurements for an accurate estimate.

A 40ft standard container is roughly double the length of a 20ft container, so it carries close to double the cargo. Buyers with larger order volumes typically use 40ft containers to bring down the per-piece freight cost, since fixed shipping charges are spread across more units

Sea freight is far more cost-effective for bulk bag orders and is the standard choice for full or partial container loads. Air freight is faster but significantly more expensive per kg, and is generally only worth it for small sample orders or urgent top-up shipments, not full bulk exports.

When bags are packed flat, they’re stacked on top of each other inside the carton — so the more pieces you pack, the taller the stack gets. The material’s thickness per piece (jute, cotton, and canvas each fold to a different thickness) determines how much height that stack adds, which is why the same quantity of different materials can need different carton sizes.
