My son is starting first grade. How do I choose the right furniture height for his home study area?
Getting the right size is important for comfort and posture. Here's a simple guide:
Standard Sizes for a 7-Year-Old (typically 120-130 cm tall):
| Furniture | Recommended Size | What to Look For |
|---|---|---|
| Desk Height | 20-22 inches (52-56 cm) | Adjustable is best—grows with child |
| Chair Seat Height | 12-14 inches (30-35 cm) | Child's feet should rest flat on floor |
| Desk Depth | 18-20 inches (45-50 cm) | Enough for books and screen |
The "90-90-90" Rule for Good Posture:
Feet flat on floor (90° at ankles)
Knees bent at 90°
Hips at 90° (thighs parallel to floor)
Elbows at 90° when hands on desk
Quick Check:
When seated, the desk should be about 2 inches above the child's elbows when arms hang naturally. This prevents hunching or reaching up.
Pro Tip: Buy an adjustable height chair and desk that can grow with your child from ages 6-12. It costs more upfront but saves money long-term.
