Packing Supply Calculator

Kitchen Size (0 = small/galley, 1 = medium, 2 = large/gourmet) is converted internally to a multiplier of kitchenSize + 1, so it's 1, 2, or 3. That multiplier is applied to fixed per-size box quantities (5 small, 4 medium, 2 large at the base level), meaning a large/gourmet kitchen generates exactly three times the boxes a small galley kitchen does — a deliberate reflection of how much more cookware, dishes, and small appliances a bigger kitchen tends to accumulate.

Bathroom contents — toiletries, towels, and linens — rarely fill a large box efficiently or need one, so the formula only computes bathSmall (3 per bathroom) and bathMedium (2 per bathroom) with no bathroom contribution to the large-box total at all. Large boxes in this calculator come exclusively from bedrooms, kitchen, garage/storage, and the flat living-area allowance.

Tape Rolls is the total box count (small + medium + large + wardrobe) divided by 10 and rounded up, on the assumption that one roll of 2-inch tape reasonably seals about 10 boxes. The calculator floors this at a minimum of 2 rolls regardless of how few boxes you're packing, since even a small studio move needs enough tape on hand to seal boxes, tape edges, and handle mistakes — buying just 1 roll rarely proves sufficient in practice.

Bubble Wrap (ft) combines kitchenMultiplier times 15, plus bathrooms times 10, plus bedrooms times 5. Kitchens and bathrooms get the heaviest weighting because glassware, dishware, and toiletry bottles cluster there, but bedrooms still contribute a smaller amount to cover framed pictures, mirrors, lamps, and other fragile items commonly stored in bedrooms.
