📏Ennui ST Set Size Chart
The Ennui ST Smiley and ST Pirate sets ship with a knee guard, elbow guard and wrist guard — each piece is sized independently in XS / S / M. Measure all three joints with a soft tape, then pick the size that matches across the most charts. If sizes split between pieces, size up for comfort.

🩊 Knee Guard
Measure: wrap a soft tape 4" (10 cm) above the centre of the kneecap for thigh (A), then 4" below for calf (B). Stand relaxed with the leg straight.

💪 Elbow Guard
Measure: wrap the tape 5" above the elbow centre for bicep (A), then 4" below for forearm (B). Keep the arm slightly bent and relaxed.

✋ Wrist Guard
Measure: open your hand flat and wrap a soft tape around the base of your knuckles (A = hand width). Then measure around the centre of the wrist (B).
✓ How it should feel
Each cap centred over the joint. Snug all-around with no pinching at the back of the joint. Stays in place when the child bends, runs or skates.
✗ How it should NOT feel
Slides down the limb when walking. Cap shifts off-centre on impact. Pins-and-needles below the strap (too tight). Bunches at the back.
