Key Capabilities

✓Selectable mesh conventions (3-dc mesh vs traditional 4-dc mesh)
✓Block-by-block tracker within active row: Open (dc, ch 2) vs Solid (3 dc)
✓Row grid preview with filled and open tile highlights
✓Symmetric chart reading helper (left-to-right on RS, right-to-left on WS)

Expert Crafting Advice

💡Read odd-numbered rows right to left and even-numbered rows left to right on traditional filet charts.
💡Keep turning chains taut to ensure crisp rectangular open mesh windows.

How the Filet Crochet Counter Works

The Filet Crochet Counter works in 4 steps.

1
Choose the mesh convention
Note "3-st mesh (dc, ch 2)" or a wider 4-stitch mesh in the notes box.
2
Write the chart row as runs
Translate the chart row into runs such as "3 open, 2 filled, 5 open".
3
Count squares
Set Target Goal to the squares in the row and tap + Count after each open or filled square.
4
Check the row
Compare the square count with the chart width before turning.

Filet Crochet Counter Formula

The Filet Crochet Counter formula converts squares into stitches and foundation chains.

Row stitches = (Squares × 3) + 1

Foundation chain (Row 1 starts with a filled block, first dc in 4th ch from hook) = (Squares × 3) + 3

Foundation chain (Row 1 starts with an open mesh, first dc in 8th ch from hook) = (Squares × 3) + 5

Squares: Chart squares across the row
3: Stitches per square in the standard convention
+1: The closing dc at the end of the row

Worked example: A chart 30 squares wide needs (30 × 3) + 1 = 91 stitches per row. The foundation chain is (30 × 3) + 3 = 93 for a filled-block start and (30 × 3) + 5 = 95 for an open-mesh start.

Filet Crochet Counter Conversion Table

The Filet Crochet Counter conversion table converts chart squares into stitches for the standard 3-stitch mesh and a wide 4-stitch mesh.

Chart squares	Stitches (3-st mesh)	Stitches (4-st mesh)	Chain, block start	Chain, mesh start
10	31	41	33	35
15	46	61	48	50
20	61	81	63	65
25	76	101	78	80
30	91	121	93	95
40	121	161	123	125
50	151	201	153	155
60	181	241	183	185

Both chain columns use the 3-stitch mesh. A filled-block start works the first dc in the 4th ch from the hook; an open-mesh start works it in the 8th ch.

What is a Filet Crochet Counter?

A filet crochet counter is a counter that tracks filled blocks and open mesh spaces across each row of a filet crochet chart. The Crochet Stitch Counter Filet Crochet Counter turns block counts into stitch counts so rows stay the right width.

Filet crochet forms pictures from a grid. An open mesh is 1 double crochet (dc) followed by chain 2, and a filled block replaces the chain 2 with 2 dc. Every square shares an edge dc with its neighbor, so a row of B squares holds 3 × B + 1 stitches in the standard 3-stitch convention.

Charts show filled squares in black and open squares in white. Counting runs of each type keeps the picture correct.
