Key Capabilities
- ✓Turn chain handling: ch 1 (sc), ch 2 (hdc), ch 3 (dc)
- ✓Option to treat turning chain as first stitch or not
- ✓Support for foundation chainless single/double crochet equivalents
- ✓Clear step-by-step chain count explanation
Expert Crafting Advice
- 💡If turning chain counts as a stitch, work your first stitch into the 4th chain from hook (for dc).
- 💡Use a hook one size larger for foundation chains to keep the edge elastic and non-curling.
How the Foundation Chain Calculator Works
The Foundation Chain Calculator works in 4 steps.
- 1
Enter the first-row stitches
Type the number of stitches Row 1 needs, such as 60.
- 2
Choose the stitch type
Enter 1 for sc, 2 for hdc or 3 for dc.
- 3
Set the turning-chain rule
Enter 1 when the turning chain counts as a stitch, or 0 when it does not.
- 4
Press Calculate Result
Read the starting chain count, then chain that number.
Foundation Chain Calculator Formula
The Foundation Chain Calculator formula adds the turning chain to the stitch count, minus 1 when the turning chain counts as a stitch.
Chains (t-ch not counted) = First-row stitches + Turning chain
Chains (t-ch counted) = First-row stitches + Turning chain − 1
- First-row stitches
- Stitches needed in Row 1
- Turning chain
- 1 for sc, 2 for hdc, 3 for dc
- t-ch
- Turning chain
Worked example: A dc row of 60 stitches where the turning chain counts as a stitch: chains = 60 + 3 − 1 = 62. Work the first dc into the 4th chain from the hook.
Foundation Chain Calculator Conversion Table
The Foundation Chain Calculator conversion table lists starting chains for common first-row counts under each stitch type and turning-chain rule.
| First-row stitches | sc (t-ch not counted) | hdc (t-ch not counted) | hdc (t-ch counted) | dc (t-ch not counted) | dc (t-ch counted) |
|---|---|---|---|---|---|
| 10 | 11 | 12 | 11 | 13 | 12 |
| 20 | 21 | 22 | 21 | 23 | 22 |
| 30 | 31 | 32 | 31 | 33 | 32 |
| 40 | 41 | 42 | 41 | 43 | 42 |
| 50 | 51 | 52 | 51 | 53 | 52 |
| 60 | 61 | 62 | 61 | 63 | 62 |
| 80 | 81 | 82 | 81 | 83 | 82 |
| 100 | 101 | 102 | 101 | 103 | 102 |
Single crochet turning chains almost never count as a stitch, so only one sc column appears.
What is a Foundation Chain Calculator?
A foundation chain calculator is a calculator that gives the number of starting chains needed for a set number of first-row stitches, based on stitch type and turning-chain rules. The Crochet Stitch Counter Foundation Chain Calculator removes the guesswork of "chain how many?"
The first stitch of Row 1 goes into a chain a set distance from the hook: the 2nd chain for single crochet (sc), the 3rd for half double crochet (hdc) and the 4th for double crochet (dc). Those skipped chains form the turning chain. Some patterns count the turning chain as the first stitch and some do not.
The calculator applies both conventions so the chain count matches your pattern's rule.
What are the Uses of a Foundation Chain Calculator?
There are 4 main uses of a Foundation Chain Calculator.
Starting any flat piece
Row 1 begins with the exact stitch count.
Following patterns that state stitches, not chains
Patterns that say "work 60 dc" become a chain count.
Switching stitch types
Changing from sc to dc changes the chain count.
Avoiding short rows
A correct chain prevents a Row 1 that ends 1 or 2 stitches short.
