24 is the example result. Read it using the units and relationship stated below.
Yarn Tree uses tree height, coverage per yarn yard.
Turning measured dimensions into a material plan
For yarn tree, the relationship is Estimated yarn yards = tree height ÷ coverage per yarn yard. Height and coverage must use the same length unit. The amount depends on the supplied tree height, coverage per yarn yard, rather than a live market price or a value imported from another record. Material quantities begin with the actual surface, volume or part dimensions. A footprint and a sloped surface are different measurements. Pack sizes, offcuts and layout can increase the order above the geometric requirement.
What the model includes
Estimated yarn yards = tree height ÷ coverage per yarn yard. Height and coverage must use the same length unit. Check the dimension convention and include openings only where the model has a corresponding input. A percentage allowance is a planning adjustment, not a layout simulation. Retain the source drawing or measurement sheet next to the result. Confirm the supplier unit before ordering. Area, volume, board feet and mass cannot be substituted without the thickness or density relationship. Structural suitability and fixing details are outside a quantity estimate.
Example with the supplied inputs
Tree height: 6; Coverage per yarn yard: 0.25. Result: 24. The values are illustrative.
Compare one changed input
Tree height changes from 6 to 6.6. The result becomes 26.4. All other inputs remain fixed.
Calculation rule
Estimated yarn yards = tree height ÷ coverage per yarn yard. Height and coverage must use the same length unit.
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Tree height | 6 | Measure tree height in the displayed unit. Convert the source measurement before entry if it uses another system; a changed label does not perform a unit conversion. |
| Coverage per yarn yard | 0.25 | Use the source quantity represented by coverage per yarn yard. Keep the counted population fixed and avoid mixing a unit value with a period total. |
Output: 24 is the example result. Read it using the units and relationship stated below. Use the formula to distinguish a cash amount, count, percentage or ratio.
How to use the page
Collect the inputs
Gather Tree height, Coverage per yarn yard. Use one period and the units shown in the form.
Run the calculation
Enter the values and select the action. The calculation rule above explains how the inputs produce the result.
Compare a scenario
Change Tree height on its own, keeping the other inputs fixed. Read both results before changing another assumption.
Worked example
With the example inputs listed above, the result is 24.
Change Tree height from 6 to 6.6 while keeping every other value fixed. The result becomes 26.4. This comparison isolates that input; it does not forecast how other variables will respond.
Check the stated formula, units and limits before using the result in a decision.
Keep the displayed formula, input units and model scope with the result. Corrections or questions can be sent through the request section on this page.
