Will a 28-Inch Suitcase Fit in a Hongdae Locker?
Short answer: Yes. A standard Seoul subway large locker (50 × 90 × 60 cm) fits a 28-inch suitcase. A 32-inch needs to be laid flat. If the expander zipper is open, good luck.
But the real bottleneck is not the dimensions — it’s that there are barely any large lockers. At a station as busy as Hongik Univ., the large ones vanish by early afternoon.
This post answers “will my suitcase fit” and nothing else. For price comparisons, see Hongdae Locker Prices 2026.
Actual locker dimensions (Seoul subway standard)
The T-Locker system run by Seoul Metro has 5,511 units across 269 stations and 332 locations. Three sizes:
| Type | Dimensions (W × D × H) | Weekday, 4 hrs | Extra per hour |
|---|---|---|---|
| Small | 50 × 30 × 60 cm | ₩2,200 | ₩500 |
| Medium | 50 × 45 × 60 cm | ₩3,300 | ₩800 |
| Large | 50 × 90 × 60 cm | ₩4,400 | ₩1,000 |
Hongik Univ. Station lockers follow this exact spec. The TLUGGAGE lockers inside and outside the station use the same three sizes (4-hour base, then ₩500/₩800/₩1,000 per extra hour). So the table above covers nearly every locker you’ll run into around Hongdae.
The AREX concourse lockers charge slightly different rates. Find them in the underground corridor between Exits 3 and 4 heading toward the AREX side. Rates: Small ₩2,000 / Medium ₩3,000 / Large ₩4,000 (4-hour base). Hours: 06:00–24:00.
This is the real choke point. Among those AREX concourse lockers, only about 20 units can take a suitcase. This is the first set of lockers most people see after getting off the airport train. Do not count on finding one empty after noon.
The large locker’s 90 cm depth is designed so you slide your suitcase in lengthwise, upright. Think of it as the suitcase’s long side going into the 90 cm dimension, not the 60 cm height.
Which locker fits which suitcase
Suitcase inch sizes are based on height (handle excluded) and vary by brand by 2–3 cm. Here are typical external dimensions:
| Suitcase | Approx. dimensions (H × W × D) | Small | Medium | Large |
|---|---|---|---|---|
| 20″ (carry-on) | 55 × 40 × 20 cm | ⭕ | ⭕ | ⭕ |
| 24″ | 65 × 45 × 25 cm | ❌ | ⭕ | ⭕ |
| 26″ | 70 × 48 × 28 cm | ❌ | △ | ⭕ |
| 28″ | 75 × 50 × 30 cm | ❌ | ❌ | ⭕ |
| 32″ (large checked) | 82 × 55 × 35 cm | ❌ | ❌ | △ |
- ⭕ = fits with room to spare / △ = fits if angled right / ❌ = no
- Expander zipper open adds 5–8 cm of depth — bumps you up one locker size.
- Backpacks and duffels are more forgiving since they squish. A 40L backpack fits in a small locker.
Fitting multiple bags in one locker
| Combo | Minimum locker size needed |
|---|---|
| Two 20″ carry-ons | Medium |
| 24″ + backpack | Large |
| Two 24″ | Large (tight — door barely closes) |
| Two 28″ | No — go to a staffed counter |
Heads-up: The door has to close without resistance for the lock to engage. Force it shut and you risk a lock error — while your payment already went through. If it does not close easily, go up a size.
When it won’t fit — where to go in Hongdae
Oversized items (beyond 28″, three or more bags, golf bags, strollers, instruments) are a job for staffed counters. Lockers charge per compartment; staffed counters charge per piece, so they actually get cheaper the more bags you have.
| Situation | Recommendation |
|---|---|
| 1 suitcase, under 4 hours | Locker (cheapest) |
| 2+ suitcases | Staffed counter (per-piece pricing) |
| Oversized or odd-shaped items | Staffed counter — message ahead |
| All lockers full (afternoon) | Staffed counter (reserve in advance) |
For a head-to-head of the three staffed counters around Hongik Univ. Station (prices, locations, hours), see Hongdae Staffed Luggage Storage Compared.
Staffed counters size their items differently
Unlike lockers with fixed compartments, staffed counters price by suitcase inch size or length:
| Provider | Size brackets |
|---|---|
| KPLANZ | S: under 20″ / M: 20–23″ / L: 23–27″ / XL: over 27″ |
| TLUGGAGE | S: ≤20″ / M: 20–23″ / L: 23–27″ / Oversized: 27″+ |
| Jimcarry | S: ≤55 cm / M: 56–70 cm / L: 71 cm+ |
The key takeaway: All three have a dedicated bracket for items over 27 inches. That means they take bags that won’t fit in any locker. If you have a 32-inch suitcase or an expanded one, skip the locker hunt and head straight to a staffed counter.
Golf bags, strollers, and instruments vary by provider, so message them first.
Summer warning — lockers get hot inside
Summer 2026 ran hotter than average. On July 31, Yangsan (Gyeongnam) hit 41.4°C, breaking the all-time daily high record for South Korea. Lockers installed above ground or outdoors get even hotter inside than the outside air.
Things you should not put in a locker during summer:
- Chocolate, macarons — anything that melts
- Cosmetics (especially lip balms and cream formulations), film
- Temperature-sensitive medication — insulin and suppositories: never
- High-capacity lithium power banks (some lockers ban these outright)
Pick an underground storage spot and you sidestep most of this. Hongik Univ. Station has underground-connected storage (Exit 3 KPLANZ, Exit 9 Yellow, AREX concourse). In summer, these are the clear winners. Same logic applies on rainy days.
Bottom line
- Up to 28 inches fits in a large locker. 32 inches, expander open, or two or more bags → staffed counter.
- Three numbers to remember: Small 50×30×60 / Medium 50×45×60 / Large 50×90×60 cm.
- The real variable is not size — it’s whether a locker is free. Weekend afternoons, do not count on finding a large one.
- In summer, keep meltable items and medication out of lockers.
