Plan laminate materials for garden cabinets and storage. Add waste, pick box size, see totals. Export your estimate to CSV or printable PDF now.
Enter dimensions, subtract cutouts, then add waste. The calculator returns the number of boxes you should buy for the project area.
| Scenario | Length × Width | Cutouts | Waste | Box coverage | Boxes needed |
|---|---|---|---|---|---|
| Small shed shelf | 6 ft × 2 ft | 0 ft² | 10% | 20 ft²/box | 1 |
| Garden cabinet panels | 8 ft × 4 ft | 2 ft² | 12% | 18 ft²/box | 2 |
| Raised bed liner area | 10 ft × 3 ft | 1 ft² | 15% | 22 ft²/box | 2 |
Box coverage is the usable surface area a carton delivers after installation. Manufacturers often report this as square feet or square meters per box. Your result improves when you confirm the stated coverage matches the plank thickness and locking profile you are buying. If two boxes share the same brand name, their coverage can still differ by product line, length mix, or bevel style.
Waste is not only offcuts. It also covers damaged corners, imperfect tongues, and pattern alignment. For simple rectangles with straight runs, 7 to 10 percent is commonly adequate. For L-shapes, diagonal layouts, or many obstructions, 12 to 15 percent reduces the risk of shortages. Ordering one extra box is often cheaper than a second delivery.
Cutout area represents spaces that will not be laminated, such as utility access panels, sink openings, or permanent equipment footprints. Subtracting these areas before adding waste prevents overbuying. When cutouts are irregular, break them into smaller rectangles, sum their areas, then enter the total. Consistent units matter, so measure all dimensions the same way. When budgeting, compare lot numbers so color and gloss stay consistent across your entire build today.
Boxes are the purchase unit, while planks describe the installed pieces. If you enter plank length and width, the optional plank count gives a second viewpoint on the same requirement. Large differences between boxes and planks usually indicate a unit mismatch or an incorrect coverage value. This cross-check is useful when you are mixing partial boxes from storage.
Cost is estimated as boxes needed multiplied by your price per box. Taxes, trim pieces, adhesives, and underlayment are not included, so treat the figure as a material baseline. For outdoor storage projects, confirm the laminate’s moisture rating and edge sealing method. Keep spare planks for future repairs, and store them flat in a dry place.
Use 7–10% for simple rectangles and straight installs. Use 12–15% for many cuts, diagonal patterns, or complex edges. If supply is uncertain, round up by one box to stay safe.
Yes, subtract any area that will not receive laminate. Estimate irregular cutouts by splitting them into rectangles and summing areas. Subtract first, then apply waste so the allowance reflects your real cut plan.
Avoid mixing units. Select Metric if the packaging lists m², or convert coverage to ft² before entering it. Consistent units prevent large overestimates and make the optional plank check meaningful.
The plank count is a cross-check based on plank area. Differences usually come from rounding, mixed-unit inputs, or an incorrect coverage value. Boxes are what you buy; planks help you verify the math.
No. The cost is boxes needed multiplied by price per box. Add separate lines for trim, edge banding, sealant, underlayment, delivery, and taxes to complete your procurement budget.
Accuracy is high for area-based ordering, but durability depends on product choice. Confirm moisture resistance, edge sealing, and exposure limits. Keep spares for repairs, and store them flat and dry.
