Steel building sizes
Width sets the clear span, length sets the number of bays, and eave height sets what fits through the door. These are the sizes people ask about most.
Common clear-span sizes
| Size (ft) | Floor area | Typical use | Framing |
|---|---|---|---|
| 30x40 | 1,200 sq ft | Two-bay garage shop, hobby shop, small equipment storage | red iron or light gauge |
| 40x60 | 2,400 sq ft | Acreage shop with RV or equipment bays, small contractor shop | red iron or light gauge |
| 60x100 | 6,000 sq ft | Contractor yard building, machine storage, small warehouse | red iron |
| 100x200+ | 20,000 sq ft | Warehouse, crane-served fabrication shop, riding arena | red iron |
Every size is a starting point. Width, length, eave height and frame spacing are set to your use and your site.
