patterns, shaping a sweater yoke, or adjusting a ready-made pattern to fit perfectly. Our Raglan Depth Calculator provides instant and accurate measurements validated by modern garment-construction techniques. Whether you’re a beginner knitter, an advanced pattern designer, or someone adjusting a sewing pattern for better comfort, this tool helps you determine the correct depth based on chest size, armhole shaping, and project gauge.

What Is Raglan Depth?

Raglan depth is the diagonal measurement from the neckline to the underarm along the raglan seam line. It determines how a raglan sleeve fits the body and affects both mobility and the overall silhouette. A deeper raglan depth offers more room and a relaxed fit, while a shorter depth creates a tighter, more structured yoke.

This measurement is crucial in:

  • Knitting top-down or bottom-up raglan sweaters

  • Adjusting sewing patterns for raglan-sleeve garments

  • Drafting custom garment templates

  • Achieving correct arm movement and shoulder comfort


Why Accurate Raglan Depth Matters

Getting this measurement wrong can lead to:

  • Tight underarms

  • Excess fabric pooling near the chest

  • Twisted seams

  • Shoulder discomfort

  • A neckline that stretches out over time

Our advanced calculator solves this using precise formulas and optional interactive visual depth preview.

How to Use the Raglan Depth Calculator

  1. Enter the body measurement (chest/bust size).

  2. Select your gauge or stitch count per inch/cm (for knit projects).

  3. Choose whether you’re using a top-down or bottom-up construction method.

  4. (Optional) Drag the points on the raglan depth visual chart to match your preferred fit.

  5. Click Calculate to see:

    • Recommended raglan depth

    • Seam shaping details

    • Stitches to increase/decrease

    • Total yoke rows or rounds

This makes it easy to draft perfect raglan sleeves without complex math.

Who Can Use This Calculator?

This tool is designed for:

  • Knitting designers creating custom patterns

  • Pattern graders producing multiple sizes

  • Clothing manufacturers creating digital templates

The interface is 100% mobile responsive, allowing quick use on phones while crafting.

Raglan Depth Formula (Explained Simply)

While raglan depth varies by construction style, a common base formula is:

Raglan Depth = (Chest Circumference ÷ 4) × Fit Adjustment

Fit adjustment typically ranges between:

  • 0.28 – 0.32 for a fitted garment

  • 0.33 – 0.36 for regular fit

  • 0.37 – 0.40 for relaxed/oversized fit

Our tool automatically applies fit ease, gauge adjustments, and shaping optimization to give a highly accurate measurement.

Tips for Getting a Perfect Raglan Fit

  • Use a soft measuring tape and measure the chest/bust at the fullest part.

  • Select a gauge swatch of at least 4 × 4 inches for accurate stitch count.

  • Consider adding 1–2 cm for layering or oversized projects.

  • For children’s garments, add small ease for growth.

  • Always block knitted pieces before final assembly.


Common Questions About Raglan Depth (FAQ)

1. Is raglan depth the same for men and women?

The method is the same, but ease is usually higher for men due to shoulder width differences.

2. How deep should a raglan sleeve be?

Most adult sweaters fall between 7–11 inches (18–28 cm), depending on size and fit style.

3. Why does my raglan look too loose?

You may have used too much ease or too deep a measurement. Our calculator helps correct this instantly.

4. Can I use this calculator for sewing?

Yes! Raglan depth applies to both knitting and sewing; only the shaping method differs.

5. Does yarn weight change raglan depth?

Yarn weight affects gauge, which impacts row count but not the core raglan depth ratio.
