Sony Selex Complete Size Chart: Waist Size 22 to 40 Guide for Retailers

Getting the size right is the first step to a satisfied school uniform customer. A pair of slacks that fits correctly lasts longer, looks neater, and earns repeat business. This guide provides a complete reference for SONY Selex school slacks sizing — covering the full waist size range from 22 to 40, approximate age-to-size mapping, fit differences across the three SONY Selex cuts, and practical advice for retailers on which sizes to stock in what quantities.

The SONY Selex Size System

SONY Selex school slacks are sized by waist circumference in inches. This is a direct measurement — size 28 means a 28-inch waist. The range runs from size 22 to size 40, covering students from approximately 5 years to adult women, making the range suitable for every school demographic from junior classes through senior secondary.

The sizing system is consistent across all three fits (Classic, Slim, Comfort) and all 10+ colours, which simplifies reordering — a customer who wears size 28 in navy blue Classic can order size 28 in bottle green Slim without a fitting, which is a practical advantage for institutional bulk orders.

Complete Size Chart: Waist Size to Age Mapping

Note: These are approximate age-to-size mappings based on average Indian school student body measurements. Individual children vary. Always measure the waist directly rather than buying by age alone.

How to Take a Correct Waist Measurement

Use a soft measuring tape. Have the student stand naturally, not sucking in or expanding the stomach. Measure at the natural waist — the narrowest point of the torso, typically 1–2 inches above the navel. The tape should be snug but not tight enough to compress the skin.

Add 1 inch (approximately 2.5 cm) to the measured waist for comfortable school wear. For example, a student with a 27-inch waist measurement should select size 28. For the Comfort fit, which has a slightly more relaxed waist construction, some customers prefer the exact measurement size.

If a student is between sizes, always go up one size for school slacks. Slacks can be hemmed shorter but cannot be let out at the waist if too tight, and tight slacks are uncomfortable for a full school day.

Fit Comparison: Classic vs Slim vs Comfort

The three SONY Selex fits share the same waist size system but differ in cut:

• Classic Fit: Straight leg from hip to ankle, moderate seat room, works for most body types. The default recommendation for students who have never tried SONY Selex before.
• Slim Fit: Tapered leg, closer fit through the thigh and calf. Preferred by older students (Class 9–12) who want a more contemporary look. Not suitable for students with athletic or fuller builds at this size.
• Comfort Fit: Slightly wider through the hip and thigh, straight leg. Ideal for students who find Classic restrictive or for longer school days involving physical activity. Popular for younger students and teacher orders in larger sizes.

When advising a first-time buyer, recommend Classic if you are unsure. If the customer returns saying the fit is too straight or too loose in the leg, you can guide them toward Slim or Comfort respectively on the next purchase.

Stocking Advice for Retailers: Which Sizes to Order

Demand is not evenly distributed across all 10 sizes. Based on typical retail patterns at school uniform shops across north India, sizes 26 to 32 account for the majority of units sold — this is the range covering Classes 4 through 9, which is the largest student population in most schools.

A suggested opening stock distribution per colour for a new retailer:

• Sizes 22–24: 10% of stock (junior classes)
• Sizes 26–30: 50% of stock (core school sizes, high turnover)
• Sizes 32–36: 30% of stock (senior classes)
• Sizes 38–40: 10% of stock (senior students and teacher orders)

Adjust this distribution based on your school catchment — a senior secondary only school will shift demand toward sizes 32–40, while a primary school will concentrate demand in sizes 22–28. Track your sell-through rate by size for the first season and refine your next order accordingly. For sizing details on specific fits, see our complete girls sizing guide.
