> Editor note: garment measures are cm only (no inch column on supplier charts). Bottoms list pants length (pants length) — total pants length as labeled on supplier charts, not true inseam (not confirmed). Weight ranges on charts are as printed; unit not labeled on image except T019/T020 (jin) — those SKUs are not featured here.
Matching sets are often cut roomy, and pant length is one of the most common reasons people send a set back. The fix is simple: choose your top size and your bottom size separately. This guide shows you how.
> Charts below are transcribed from supplier size images (2026-10-23). Style codes vary — always check the PDP chart for the exact SKU you are buying.
How Kaizo sizing works
- Tops and bottoms are separate products. Each has its own size chart.
- Pair by color. Pick the same color on both pieces to complete the set.
- Mix sizes freely. A medium top with a large bottom, or a large top with a small bottom — whatever fits you.
There’s no single bundled set size, so you’re never stuck with one size that fits half your body.
Read this before you size up: the oversized expectation
Many matching sets are designed with a relaxed, lounge fit.
- Want the relaxed, oversized look? Take your usual size.
- Want a closer fit? Size down one.
Tops size chart (example: W2)
Homepage top W2 — primary example. Other homepage tops (W1, W3, W17) have their own charts; numbers differ slightly by style. Always prefer the chart on the product page.
| Size | Chest (cm) | Length (cm) | Shoulder (cm) | Sleeve (cm) | Height guide (cm) | | — | — | — | — | — | — | | S | 119 | 70 | 57 | 58 | 160–165 | | M | 124 | 72 | 59 | 59 | 170–175 | | L | 129 | 74 | 61 | 60 | 175–180 | | XL | 134 | 77 | 63 | 61 | 180–185 | | 2XL | 139 | 79 | 65 | 62 | 185–190 |
Also available (homepage tops): W1 and W3 use the same column set (Chest / Length / Shoulder / Sleeve + height guide). W17 has Chest / Length / Shoulder / Sleeve only (no height/weight columns on its chart). Charts vary by style — see the PDP.
How to measure: lay your favorite sweatshirt flat. Measure across the chest from armpit to armpit, and from the high point of the shoulder to the hem. Compare with the chart (cm).
Bottoms size charts + pants length (pants length)
Supplier bottoms charts label pants length (pants length) — total pants length as printed, not true inseam. Do not treat these numbers as crotch-to-hem inseam unless the brand confirms otherwise.
Adult bottoms differ a lot by style, so each style gets its own mini-table. Focus styles below: K8 and K20 (longer pants) · K6 and K055 (shorter / cropped lengths).
K8 — longer pants (pants length ~94–106 cm)
| Size | Waist (cm) | Hip (cm) | Pants length pants length (cm) | Height guide (cm) | | — | — | — | — | — | | S | 70 | 102 | 94 | 160–165 | | M | 74 | 106 | 97 | 170–175 | | L | 78 | 110 | 100 | 175–180 | | XL | 82 | 114 | 103 | 180–185 | | 2XL | 86 | 118 | 106 | 185–195 |
K20 — longer pants (pants length ~103–111 cm)
| Size | Waist (cm) | Hip (cm) | Pants length pants length (cm) | Height guide (cm) | | — | — | — | — | — | | S | 65 | 104 | 103 | 160–165 | | M | 69 | 108 | 105 | 170–175 | | L | 71 | 112 | 107 | 175–180 | | XL | 74 | 116 | 109 | 180–185 | | 2XL | 78 | 120 | 111 | 185–195 |
K6 — shorter length (pants length ~43.5–49.5 cm)
Likely shorts / cropped silhouette based on pants length — label follows the supplier chart, not a style name invent.
| Size | Waist (cm) | Seat (cm) | Pants length pants length (cm) | Height guide (cm) | | — | — | — | — | — | | S | 64 | 55 | 43.5 | 165–170 | | M | 68 | 57 | 45 | 170–175 | | L | 72 | 59 | 46.5 | 175–180 | | XL | 76 | 61 | 48 | 180–185 | | 2XL | 80 | 63 | 49.5 | 185–190 |
K055 — shorter length (pants length ~49–53 cm)
| Size | Waist (cm) | Hip (cm) | Pants length pants length (cm) | Height guide (cm) | | — | — | — | — | — | | S | 66 | 106 | 49 | 160–165 | | M | 70 | 110 | 50 | 170–175 | | L | 74 | 114 | 51 | 175–180 | | XL | 78 | 118 | 52 | 180–190 | | 2XL | 82 | 122 | 53 | 180–190 |
Length tip: a cuffed jogger can stack a little extra length at the ankle; a straight / wide-leg hang shows length more clearly. Always match pants length on the chart for the exact style you are buying.
Quick height guidance (from supplier height guide, cm):
- Around 160–165 cm: start with S on the longer styles (K8 / K20); check pants length carefully on cropped styles.
- Around 170–175 cm: M is the chart’s typical band on most adult bottoms above.
- Around 175–180 cm: L band on most adult bottoms above.
- 180 cm and up: XL / 2XL bands; prioritize pants length on longer styles (K8 / K20).

Mix sizes: build a better set
- Size the top down if you have a shorter torso or narrower shoulders and want a cleaner shape.
- Size the bottom up if you need more room through the hips or want a longer pants length.
- Size the top up for a slouchy, oversized hoodie look over a fitted bottom.
Keep the color the same and the set still reads as one outfit.
