A Step-by-Step Guide to Measuring Your Hand for the Perfect Fit

An ill-fitting glove doesn’t just cause hand fatigue and discomfort—it can actively compromise your safety. Gloves that are too tight can cut off blood circulation and restrict hand movement. On the other hand, oversized gloves can slip off at the slightest movement, reducing your dexterity and making your handling clumsy and imprecise.

At SHOWA, we design our gloves to provide maximum protection, comfort, and productivity. To help you get the most out of your protective gear, we’ve put together this simple guide to help you find your exact glove size using the SHOWA Glove Size Chart.

Why Glove Sizing Matters for Workplace Safety
Choosing the right personal protective equipment (PPE) means looking at more than just the material. Proper fit directly impacts your performance:

• Enhanced Dexterity: Correctly fitted gloves allow you to handle small parts, tools, and machinery with precision.
• Reduced Hand Fatigue: Prevent the muscle cramping and all-day pain caused by struggling against a glove that is too small or too loose.
• Optimal Protection: Properly fitted cuffs and palms ensure that chemical, mechanical, or impact hazards don’t find a way inside your glove.

Method 1: The Measuring Tape (Hand Circumference & Length)
1. Measure Hand Circumference: Wrap a flexible measuring tape around your palm, positioning it exactly 20 mm from the crotch between your thumb and index finger. Record the measurement in millimeters (mm).
2. Measure Hand Length: Measure the distance from your wrist crease to the tip of your middle finger. Record the measurement in millimeters (mm).

Method 2: The SHOWA Placement Diagram
If you have a printed copy of the SHOWA Glove Size Chart on letter (A4 equivalent in Europe) sized paper:

1. Place your right hand directly onto the diagram.
2. Align the green line so it rests perfectly in the web between your thumb and index finger.
3. Look to the right side of the chart—the numbered line where the outer edge of your hand rests indicates your SHOWA glove size (Sizes 6 through 11).

SHOWA Glove Size Conversion Chart

SHOWA gloves follow precise hand sizing metrics outlined in the BS EN ISO 21420 framework. Use your measurements from the steps above to find your corresponding size code in the reference chart below.

Important Note on Letter Sizing (S–XXL): Depending on the model, industry, and regional manufacturing site, retail letter sizing names can vary (for instance, some lines tag Size 8 as a Medium while others tag it as a Large). To ensure absolute accuracy and optimal levels of comfort and tactility, always rely primarily on the numerical SHOWA Size Code matched to your literal hand millimeter measurements.

Pro Tip: If your measurements fall between two sizes, or if you prefer a slightly looser fit, we recommend rounding up to the next size to prevent hand strain. Half sizes can also be derived by interpolation if necessary.

Smart Features of SHOWA Gloves
Finding your size is only the first step. SHOWA builds smart design features into our products to make size management easy for safety managers and workers alike:
