THE NUMBERS, EXPLAINED
How to use this calculator.
Use 1 for stitching over one Aida block; use 2 for stitching over two threads on an evenweave counted in threads per inch. Margins are added to both sides.
Start with your inputs
Enter design width (stitches), design height (stitches), fabric count per inch, threads or blocks per stitch, margin each side (inches). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Design width (stitches) | 140 |
| Design height (stitches) | 70 |
| Fabric count per inch | 14 |
| Threads or blocks per stitch | 1 |
| Margin each side (inches) | 2 |
A worked example
With the example inputs above, stitched width (inches) is 10. Change the inputs to explore your own scenario.
Putting the example numbers into the formula
Stitched width (inches)
(140) × (1) ÷ (14) = 10
Stitched height (inches)
(70) × (1) ÷ (14) = 5
Cut width (inches)
(140) × (1) ÷ (14)+2 × (2) = 14
Cut height (inches)
(70) × (1) ÷ (14)+2 × (2) = 9
| Result | Example answer |
|---|---|
| Stitched width (inches) | 10 |
| Stitched height (inches) | 5 |
| Cut width (inches) | 14 |
| Cut height (inches) | 9 |
How this is calculated
Stitched width (inches)
a × d ÷ c
Stitched height (inches)
b × d ÷ c
Cut width (inches)
a × d ÷ c+2 × e
Cut height (inches)
b × d ÷ c+2 × e
Symbols and units
- a
- Design width (stitches)
- b
- Design height (stitches)
- c
- Fabric count per inch
- d
- Threads or blocks per stitch
- e
- Margin each side (inches)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
Use 1 for stitching over one Aida block; use 2 for stitching over two threads on an evenweave counted in threads per inch. Margins are added to both sides.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Stitched width (inches); Stitched height (inches); Cut width (inches); Cut height (inches). The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Use 1 for stitching over one Aida block; use 2 for stitching over two threads on an evenweave counted in threads per inch. Margins are added to both sides.
