Youth Small (Youth S) fits children aged approximately 5–7 years, with a height of 110–122 cm, chest of 58–64 cm, and weight of 18–24 kg. In India, this corresponds to the 5–6Y or 6–7Y label. At JusCubs, Youth Small is available across the Young Boys (4Y–12Y) T-Shirts & Polo and Young Girls (4Y–12Y) T-Shirts & Polo collections — soft cotton, skin-safe, starting from ₹349.
What Is Youth Small Size?
Parents searching "what is youth small size" are usually at the point where their child has just moved out of toddler sizing and into the children's/youth section — and the letter-based sizing system (XS, S, M, L, XL) has replaced the familiar age labels (3T, 4T, 5T).
Youth Small is the second size in the youth/children's letter-size system, sitting directly above Youth XS and below Youth Medium. It is designed for school-age children who are fully potty-trained, active, and growing steadily — children who need garments proportioned for a longer torso, longer sleeves, and a slimmer overall fit than the toddler range provides.
In India, most kids clothing brands — including JusCubs — use age-year labels rather than letter sizes. Youth Small at JusCubs corresponds to the 5–6Y and 6–7Y labels in the Young Boys (4Y–12Y) and Young Girls (4Y–12Y) ranges.

Youth Small Size: Exact Measurements
The following measurements define Youth Small (Youth S) across height, weight, chest, waist, and shirt-specific dimensions:
| Measurement | Youth Small (Youth S) |
|---|---|
| Age Range | ~5–7 years |
| Height | 110–122 cm (43.5–48 in) |
| Weight | 18–24 kg (40–53 lbs) |
| Chest | 58–64 cm (23–25 in) |
| Waist | 54–58 cm (21–23 in) |
| Hip | 60–66 cm |

💡 Always measure first. Two children aged 6 can differ by 3–4 kg and 6–8 cm. Weight and height measurements are far more reliable than age alone for finding the correct youth small size.

What Size Is a Youth Small? Age & Physical Profile
"What size is a youth small" means different things depending on whether you are asking about age, height, or weight. Here is the full picture:
By Age: Youth Small fits most children aged 5 to 7 years. However, a tall 5-year-old may already need Youth Small, and a smaller 7-year-old may still be comfortable in Youth XS. Age is a starting point — not a final answer.
By Height: The most reliable indicator. Youth Small fits children standing between 110 cm and 122 cm. Below 110 cm → Youth XS (4–5Y). Above 122 cm → Youth Medium (7–8Y).
By Weight: Youth Small fits children weighing 18–24 kg. Below 18 kg at this height indicates a slim build — still Youth Small but consider sizing up in garments with a defined waist. Above 24 kg at this height indicates a broader build — consider Youth Medium.
By School Year in India: Children in Class 1 (age 6) and Class 2 (age 7) in Delhi, Noida, Gurugram, and across NCR are almost universally in Youth Small — the size that covers the first two years of primary school. It is the most-needed size in a school wardrobe.
⚠️ Indian growth note: Indian children, on average, tend to run slightly smaller than international WHO growth reference charts. A child measured at 115 cm and 20 kg will be solidly in Youth Small regardless of whether they are 5, 6, or 7 years old.
How Big Is Youth Small? — A Parent's Practical Guide
"How big is youth small" is the physical question — what does the garment actually look like and feel like on a child?
Youth Small garments are noticeably larger than anything in the toddler or infant range. Key physical differences parents notice when moving to Youth Small:
Torso length is longer. Youth Small tops cover the full torso of a 5–7 year old without riding up. A child who kept finding their 4T or Youth XS top untucking during play will find Youth Small stays in place.
Sleeves reach the wrist. Full-sleeve Youth Small tops reach to the wrist on a 110–122 cm child. Half-sleeve tops cover the full shoulder and upper arm properly — no more sleeves that stop mid-shoulder.
Waist is defined but not fitted. Youth Small bottoms have a waistband that sits at the natural waist of a 5–7 year old. Most use a partial elastic at the back or a full elastic waist — not a tight fitted waist — because children at this age are still growing quickly.
Chest has room for movement. A Youth Small top with a 58–64 cm chest allows the arm-raising, running, and jumping of an active primary school child without pulling at the seams. This is significantly more range of motion than a toddler-cut garment of the same stated chest measurement.
Youth Small T-Shirt Size: Exact Shirt Measurements
Parents specifically searching "t shirt size youth small" or "shirt size youth small" need the garment dimensions — not just the body measurements. Here are the exact shirt measurements for Youth Small:
| T-Shirt Measurement | Youth Small (5–6Y) | Youth Small (6–7Y) |
|---|---|---|
| Chest (garment) | 60–62 cm | 62–64 cm |
| Shoulder Width | 30–31 cm | 31–32 cm |
| T-Shirt Length (body) | 50–54 cm | 54–58 cm |
| Half Sleeve Length | 14–16 cm | 16–18 cm |
| Full Sleeve Length | 36–40 cm | 40–44 cm |
| Neck Opening | 28–30 cm | 29–31 cm |
💡 For school uniform T-shirts in Delhi NCR: Most primary schools in Delhi, Noida, and Gurugram require a formal collar shirt or round-neck T-shirt. For Class 1–2 students (age 6–7), Youth Small (6–7Y) at JusCubs covers both the school year and two-three years of casual wear.

How to Measure for Youth Small
Step 1 — Height: Stand your child upright against a wall, feet flat, no shoes. Measure from floor to the top of the head in centimetres. Between 110–122 cm = Youth Small (5–6Y or 6–7Y).
Step 2 — Chest: Wrap a soft tape measure around the fullest part of the chest, just under the arms, horizontally. Between 58–64 cm = Youth Small.
Step 3 — Waist: Measure around the natural waistline — the narrowest part of the torso above the belly button. Between 54–58 cm = Youth Small.
Step 4 — Determine 5–6Y or 6–7Y: If your child is between 110–116 cm and 18–21 kg, choose 5–6Y. If they are between 116–122 cm and 21–24 kg, choose 6–7Y. When in doubt, size up — children at this age grow 6–8 cm per year and a slightly larger garment extends wear time significantly.
Step 5 — For T-shirts specifically: Check the shoulder width. Sit your child on a chair and measure from the tip of one shoulder to the other across the back. Below 30 cm → still Youth XS territory. 30–32 cm → Youth Small. Above 32 cm → consider Youth Medium.
🌡️ Delhi NCR seasonal note: In North Indian summers (April–September, temperatures 40°C+), size up in Youth Small cotton T-shirts by one sub-size — choose 6–7Y even if measurements suggest 5–6Y. The extra room dramatically improves airflow and reduces heat build-up against the skin for children playing outdoors in Delhi, Noida, Gurugram, and Ghaziabad.

What to Expect in the Youth Small Phase: Parent Notes
School begins. For most Indian children, Youth Small (5–7Y) coincides with Class 1 and Class 2 — the first two years of formal schooling. Children in Delhi, Noida, and Gurugram schools typically need 2–3 formal shirts or T-shirts per school day. Stock accordingly.
Growth is fast but more predictable. Unlike the unpredictable growth spurts of the toddler years, children aged 5–7 grow an average of 6–8 cm per year. This means Youth Small, covering a 12 cm height range, typically lasts 12–18 months — longer than most toddler sizes.
Independent dressing begins. Children in Youth Small are learning to dress themselves. Garments with simple pull-on waistbands, uncomplicated necklines, and easy fasteners matter. Avoid garments with fiddly buttons at the back or complex layering at this stage.
Physical activity increases sharply. Class 1–2 children have PT periods, recess play, and after-school activities. Seam strength and fabric durability matter more at Youth Small than at any previous size. JusCubs' Young Boys Clothing Sets and Young Girls Clothing Sets are built with reinforced seams for exactly this phase.
Party and occasion wear becomes important. Birthday parties, school events, and family functions become a regular part of a 5–7 year old's calendar. Stock at least one Young Boys Party Wear or Young Girls Party Wear outfit in Youth Small.
