Creating accurate size charts is one of the most impactful things you can do for your clothing store. This guide covers everything from basic measurement techniques to advanced tips for professional results.

🛠️ What You'll Need

Before you start, gather these essential tools:

Flexible Measuring Tape

At least 60" (150cm) long. Soft tailor's tape works best.

Flat, Clean Surface

Large table or floor space. Avoid carpets that can distort measurements.

Sample Garments

One of each size you'll sell. Unworn and properly pressed.

Spreadsheet or Tool

Excel, Google Sheets, or a size chart maker.

📐 Essential Measurement Guide

Master these key measurements—they're the foundation of every size chart:

A Chest Width (Pit to Pit)

The most important measurement for tops. Determines how fitted or relaxed the garment will feel.

  1. 1 Lay garment face-up, completely flat
  2. 2 Find the point 1" below each armhole
  3. 3 Measure straight across, side seam to side seam

Side to Side
1" below armpit
B Body Length (HPS to Hem)

Measures the total length of the garment from top to bottom.

  1. 1 Find the HPS (highest point of shoulder—where collar meets shoulder seam)
  2. 2 Measure straight down to the bottom hem
  3. 3 Keep tape flat—don't follow curves

Top to Bottom
Shoulder to hem
C Shoulder Width

Determines how the garment sits on the wearer's shoulders.

  1. 1 Lay garment face-down (back facing up)
  2. 2 Find both shoulder seams
  3. 3 Measure straight across from seam to seam

Seam to Seam
Across the back
D Sleeve Length

For long-sleeve garments. Critical for jackets and dress shirts.

  1. 1 Extend the sleeve flat (don't stretch)
  2. 2 Start at shoulder seam
  3. 3 Measure along outer edge to cuff end

✍️ Method 1: Manual Measurement

The traditional approach—measure each garment yourself and create the chart manually.

Step-by-Step Process

1

Prepare Your Workspace

Clear a large flat surface. Gather all sample garments, measuring tape, and your spreadsheet or notepad.

2

Start with Size S

Begin with your smallest size. Lay it perfectly flat, smooth out wrinkles. Take all measurements.

3

Record Each Measurement

Write down chest width, body length, shoulder width, and any additional measurements immediately. Don't rely on memory.

4

Repeat for All Sizes

Move through M, L, XL, etc. Use the exact same measurement points for consistency.

5

Verify the Grade

Check that measurements increase consistently between sizes (usually 1-2" per size). Large jumps may indicate measurement errors.

Format & Design

Create a clean table in your spreadsheet, add your branding, and export as an image or PDF.

📊 Example: T-Shirt Measurements

Measurement S M L XL 2XL
Chest Width 18" 20" 22" 24" 26"
Body Length 27" 28" 29" 30" 31"
Shoulder Width 16" 17" 18" 19" 20"
Sleeve Length 8" 8.5" 9" 9.5" 10"

Measurements shown in inches. Tolerance: ±0.5"

Pros of Manual Method

  • 100% accurate to your actual garments
  • No cost (just time)
  • Full control over measurements

Cons of Manual Method

  • Time-consuming (15-30 min/garment)
  • Requires design skills for formatting
  • Risk of measurement errors
