⚡ Quick Answer
Youth Small fits children aged approximately 5–7 years, height 110–122 cm, body chest 58–66 cm. At JusCubs it maps to two labels: 5–6Y (height 110–116 cm) and 6–7Y (height 116–122 cm) — both in the Young Boys T-Shirts & Polo and Young Girls T-Shirts & Polo collections.
What Is Youth Small Size? The Precise Definition
Youth Small is the second size in the children's letter-size system — sitting above Youth XS and below Youth Medium. It is not an adult small. It is not a toddler size. It is specifically the children's size for school-age kids aged 5–7 years who have moved fully out of toddler sizing and into the structured children's range.
In India, this size is not labelled "Youth Small" on garment tags. JusCubs uses the age-year label system — 5–6Y and 6–7Y — which maps directly to the same measurement range. The label varies; the measurements do not.

What Size Is Youth Small Compared to Adjacent Sizes?
| Size | JusCubs Label | Height | Body Chest | Full Sleeve |
|---|---|---|---|---|
| Youth XS | 4–5Y | 104–110 cm | 56–60 cm | 36–40 cm |
| Youth Small | 5–6Y / 6–7Y | 110–122 cm | 58–66 cm | 40–48 cm |
| Youth Medium | 7–8Y | 122–128 cm | 64–68 cm | 48–52 cm |
Key transitions: Moving from Youth XS to Youth Small: height crosses 110 cm, full sleeve grows 4+ cm — sleeves ending above the wrist on Youth XS is the clearest signal to move up.
Moving from Youth Small to Youth Medium: height crosses 122 cm. Chest measurement is the tiebreaker when a child is at exactly the boundary — above 64 cm moves to Youth Medium.
T-Shirt Size Youth Small: Garment-Specific Fit Notes
What size is a youth small T-shirt in practical terms — what does the garment look like on a child?
Crew-neck T-shirts: The neckline sits flat at the base of the neck. No pulling, no gaping. If the neckline pulls forward when the child raises their arms, the garment chest is too small — size up.
Polo shirts: The collar sits at the mid-neck. The placket should lie flat with no pulling at the chest button. Polo shirts run slightly smaller than crew-neck T-shirts at the same label due to the collar construction — if your child is at the upper boundary of Youth Small in chest, size up to Youth Medium in polos.
Half-sleeve T-shirts: Sleeve end should reach mid-upper arm — approximately 14–18 cm from the shoulder seam. Sleeves ending at the shoulder or below the elbow indicate the wrong size.
Full-sleeve T-shirts: Sleeve end should reach the wrist bone. This is the most size-sensitive measurement in the long-sleeve format. Check full sleeve length (40–48 cm for Youth Small) before buying. Children's arms frequently grow faster than their chests — see the complete guide on long sleeve graphic tees for kids for detailed sleeve-sizing advice.

Which Youth Small Sub-Size: 5–6Y or 6–7Y?
Both 5–6Y and 6–7Y are Youth Small. Here is when to choose each:
Buy 5–6Y when: height is 110–116 cm AND chest is 58–62 cm. This is the Class 1 size for most children in Delhi NCR schools.
Buy 6–7Y when: height is 116–122 cm AND chest is 62–66 cm. This is the Class 2 size for most children in Delhi NCR schools.
Buy 6–7Y even if chest says 5–6Y when: full-sleeve T-shirts are needed and arm length exceeds 44 cm. Sleeve length is the deciding factor for full-sleeve garments.
Buy 6–7Y when in doubt between the two. Children grow 6–8 cm per year at this age — the slightly larger garment provides additional wear time at no fit cost in a casual T-shirt.
💡 Transitioning from 4T? If your child was recently in the toddler range, read What Is a 4T in Youth Sizes? before buying Youth Small — some children transition directly from 4T to Youth Small, skipping Youth XS entirely.
How to Measure for Youth Small in Two Minutes
Height: Stand your child against a wall, no shoes. Mark the top of the head. Measure floor to mark. Between 110–122 cm = Youth Small.
Chest: Soft tape measure around the fullest part of the chest, under the arms, horizontal. Between 58–66 cm = Youth Small.
Sleeve (full sleeve only): Measure from shoulder tip to wrist bone with arm hanging naturally. Between 40–48 cm = Youth Small. Above 48 cm = move to Youth Medium for full-sleeve garments.
🌡️ Delhi NCR tip: For children in Delhi, Noida, and Gurugram buying T-shirts ahead of summer (March–April), size true to measurement for outdoor wear. For AC environments — schools, malls, cars — buy one sub-size up (6–7Y if currently 5–6Y) for a layer that doubles as next-season outdoor wear.
