## Introduction<\/p>\n
Every stone importer who’s ever paid to ship air knows the frustration: you book a 40ft container, but your tiles only fill 70% of it. Or you book a 20ft container and the factory tells you the tiles won’t fit \u2014 you need another $1,800 container or you leave product behind.<\/p>\n
The root cause is almost always the same: importers don’t calculate their cargo’s actual cube and weight before booking containers. They rely on rough rules of thumb that don’t account for crate configurations, tile thickness variations, or the weight limits that actually constrain loading.<\/p>\n
This calculator guide gives you the formulas, reference tables, and practical tools to calculate exactly how much stone fits in each container type \u2014 before you place your order, before you book your freight, and before you get a surprise at the factory loading bay.<\/p>\n

For tiles packed in standard export wooden crates (the most common packing method for international stone shipments):<\/p>\n
Reference data for estimation:<\/strong><\/p>\n Tile format vs. sqm per crate (12mm thickness, standard format):<\/strong><\/p>\n Note: Crate count per container varies with loading pattern. Figures above assume floor-loading (no pallets).<\/em><\/p>\n For a 20ft container (33.2 CBM usable):<\/strong><\/p>\n For a 40ft GP container (67.7 CBM usable):<\/strong><\/p>\n For a 40ft HC container (73.0 CBM usable):<\/strong><\/p>\n Tile thickness directly affects how many tiles fit per crate and therefore how much you load per container. This is commonly underestimated.<\/p>\n Example<\/strong>: An order of 800 sqm of 20mm marble tiles was planned for a 40ft container. At 45 kg\/sqm \u00d7 800 sqm = 36,000 kg. The 40ft weight limit is 30,200 kg. You can’t fit 800 sqm. The actual load is limited to ~670 sqm by weight. The importer was 130 sqm short.<\/p>\n The most important document you can request from your factory before shipping is a container loading plan<\/strong>. This document shows:<\/p>\n A good factory will provide this for free as part of their export documentation. It typically looks like a top-down diagram of the container floor showing each crate position.<\/p>\n What to check in the loading plan:<\/strong><\/p>\n What to do if the loading plan shows poor utilization<\/strong> (< 80%):<\/p>\n Standard crates have some wasted space between them. Ask the factory to pack crates as tightly as possible and use the full container width. A difference of 10cm per crate row across a container can mean 20\u201330 extra sqm of tiles.<\/p>\n For tile crates, the factory can use alternating layer patterns that lock the crates together and use space more efficiently. This can improve utilization by 3\u20135%.<\/p>\n The high cube costs only 10\u201315% more but gives you 8\u201312% more volume. If you’re shipping 800 sqm or more, the extra cost per sqm is almost always worth it.<\/p>\n If you have multiple orders from the same factory within a short time window (4\u20136 weeks), consider consolidating into one larger container rather than shipping several smaller ones. This reduces per-sqm freight and handling costs.<\/p>\n Container doors are 2.35m wide \u00d7 2.39m high (20ft) or 2.35m \u00d7 2.39m (40ft). If your crates are slightly larger than standard, verify they can actually pass through the door before the factory loads them. A crate that doesn’t fit through the door is a serious problem.<\/p>\n Container loading calculations are not complicated, but they require attention to detail. The key steps:<\/p>\n A 40ft container that saves you $500 in freight but sits half-empty is not a win. A 20ft that fits your cargo exactly, at the right price, is the goal.<\/p>","protected":false},"excerpt":{"rendered":" ## Introduction Every stone importer who’s ever paid to ship air knows the frustration: you book a 40ft container, but your tiles only fill 70% of it.
