T1 is the quickest entry point: one carton type, one loading space, and a 3D result directly in the web page.
Choose an edition
Use the version that matches the cargo rules you cannot change. Move to the larger edition only when the simpler one no longer fits the job.
Single SKU Loading
One carton size in one container, pallet loading space, remaining container space, or larger box.
Mixed Carton Loading
Multiple carton types in one container, with six-orientation loading and an interactive quantity panel.
How to choose
Use T1 when
All cartons have the same length, width, and height, and you need the maximum count or the minimum space for a fixed count.
Use T3 when
Several carton sizes can be rotated freely and loaded directly into the container without an upright-only rule.
Use U3 when
Cargo is palletized or must remain upright, and you need both calculation and manual adjustment before shipping.
