An M-size suitcase generally has a capacity of around 50-70 liters and is suitable for short to medium-term trips (around 3-7 nights). It is between the S-size (suitable for carry-on luggage) and the L-size (for long trips), and is often used as checked baggage.
The exact dimensions will vary depending on the manufacturer and brand, but as a guideline they are generally 60-65cm high x 40-45cm wide x 25-30cm deep (external dimensions including casters and handles), with the total of the three sides being around 140-158cm.

1. Capacity and Travel Style
Mサイズのスーツケースは、一般的に3〜6泊程度の旅行に適したサイズです。
Sサイズでは荷物が収まりきらない場合や、着替え・靴・お土産などを余裕を持って収納したい場合に向いています。
ただし、Mサイズの寸法や容量はメーカーやモデルによって異なります。
同じMサイズでも収納できる荷物の量には差があるため、購入前に各商品の外寸・容量・重量を確認しましょう。
2. Material selection affects durability
- PC+ABS Material: Lightweight and well-balanced, most popular
- 100% Polycarbonate: Flexible and crack-resistant
- Aluminum Frame: Prioritizes luxury and durability (slightly heavier)
👉 Considering checked baggage at the airport, "impact resistance" is an important factor to consider.
3. Caster performance affects the comfort of movement.
- 360° rotating casters → essential
- Double casters → improved stability
- With stopper → convenient for trains and inclines
👉 As M size increases in weight, caster performance is particularly important.
