Crochet Increase Calculator

Your Increase Plan:

function calculateIncreases() { var current = parseInt(document.getElementById('currentStitches').value); var target = parseInt(document.getElementById('targetStitches').value); var resultDiv = document.getElementById('crochetResult'); var totalIncText = document.getElementById('totalIncResult'); var instructionText = document.getElementById('instructionResult'); var remainderText = document.getElementById('remainderNotice'); if (isNaN(current) || isNaN(target) || current <= 0 || target <= 0) { alert("Please enter valid numbers for both fields."); return; } if (target <= current) { alert("Target stitches must be greater than current stitches. Use a decrease calculator if you are reducing stitches."); return; } var totalIncreases = target – current; var spacing = Math.floor(current / totalIncreases); var remainder = current % totalIncreases; resultDiv.style.display = 'block'; totalIncText.innerHTML = "Total Increases Needed: " + totalIncreases; if (spacing === 1) { instructionText.innerHTML = "Pattern: Increase in every stitch."; } else { var scCount = spacing – 1; instructionText.innerHTML = "Pattern: Crochet " + scCount + " stitches, then work 2 stitches into the next stitch (increase). Repeat this across."; } if (remainder > 0) { remainderText.innerHTML = "Note: Your stitches don't divide perfectly. After completing the " + totalIncreases + " increases, you will have " + remainder + " leftover stitches at the end of the row/round to work normally."; } else { remainderText.innerHTML = "This fits perfectly! Your increases will be evenly spaced across the row."; } }

How to Use the Crochet Increase Calculator

Whether you are working on an amigurumi head, a circular shawl, or shaping a sweater, knowing exactly where to place your increases is essential for a professional finish. This crochet increase calculator helps you distribute "inc" stitches evenly across your current row or round.

The Math Behind Crochet Increases

The standard formula for calculating increase intervals is:

• 1. Calculate Total Increases: Target Stitches – Current Stitches = Total Increases Needed.
• 2. Determine Spacing: Current Stitches / Total Increases = Interval.

If your interval is 5, it means you need to perform an increase on every 5th stitch. This translates to working 4 single stitches (or whatever stitch your pattern uses) and then placing 2 stitches into the next stitch.

Example Calculation

Suppose you have 30 stitches and your pattern asks you to increase to 36 stitches.

1. 36 (Target) – 30 (Current) = 6 increases required.
2. 30 / 6 = 5.
3. Instruction: Work 4 stitches, then increase in the next (the 5th) stitch. Repeat 6 times.

Tips for Even Increases

If the math doesn't result in a whole number (a remainder), you have two choices. You can either work the extra stitches at the very end of the row, or distribute them at the beginning and end for a more symmetrical look. For circular projects, it is often better to "stagger" your increases in every other round to avoid creating a visible hexagonal shape.

Common Crochet Terms

• Inc (Increase): Usually means working two stitches into the same loop from the previous row.
• Sc: Single Crochet (US terminology).
• Hdc: Half Double Crochet.
• Dc: Double Crochet.
