How to measure and order: cladding courses and trim.
Which measurements and product data prevent quantity mistakes for this job?
Use the matching calculator
Use this decision sequence
- Record actual course runs, removed lengths and corner heights. Count usable stock after the specified end trim.
- Use selected board lengths, flat-slip packs and corner-unit packs. Enter the joint plan supplied for the job.
- Run each matching calculation and keep different products as separate purchase items.
- Check whole packs, stock remnants and delivery rounding before placing an order.
Keep the quantities distinct
| Quantity or assumption | How to use it |
|---|---|
| Measured need | Record actual course runs, removed lengths and corner heights. Count usable stock after the specified end trim. |
| Product basis | Use selected board lengths, flat-slip packs and corner-unit packs. Enter the joint plan supplied for the job. |
| Purchase rounding | Whole packs, rolls and stock lengths can exceed the exact material need. |
Worked comparison
Three 3 m continuous courses need three 5 m boards. Unrestricted joining and reuse would pool 9 m into two 5 m boards. The one-board difference depends entirely on an explicitly permitted joint plan; the calculator does not authorize that change.
Check before using the estimate
First-fit cutting produces a feasible stock count, not a guarantee of the smallest possible order. Corner units remain a separate product.
All dimensions, product properties, prices and specifications in this example are illustrative arithmetic inputs. Use the values from your measured plan, selected product data sheet and supplier quote. This guide does not choose construction specifications or certify safety.
