Singapore Airlines Hand Baggage Policy: What You Need to Know!

Singapore Airlines is pretty consistent with cabin baggage: the big thing is the 7 kg limit (and whether you’re allowed one or two carry-on pieces based on cabin). If you pack to the published size rule and keep your bag light, you’ll avoid almost all last-minute surprises.

For a quick cross-airline comparison, you can also reference my guide to airline carry-on luggage rules.

Singapore Airlines carry-on rules at a glance

• Carry-on pieces:
  • Suites / First / Business: 2 pieces
  • Premium Economy / Economy: 1 piece
• Carry-on weight: 7 kg (15.4 lb) per piece
• Carry-on size rule: The sum of length + width + height of each carry-on piece must not exceed 115 cm
• Personal item / “additional item”: You may bring 1 additional item (e.g., handbag, laptop bag) in addition to your carry-on allowance
• Personal item size: Max 40 × 30 × 10 cm; if it exceeds 80 cm total (L+W+H), it counts toward your main carry-on allowance
• Checks/enforcement: Singapore Airlines can check carry-ons at check-in and before boarding; oversized items may be taken and placed in the cargo hold
• Liquids: Standard 100 ml containers inside a 1-liter clear resealable bag (details below)

Singapore Airlines carry-on size limit

Singapore Airlines uses a simple size rule for each carry-on piece:

• Size: The sum of length + width + height must not exceed 115 cm per carry-on piece

A practical way to think about it: many “international carry-on” rollers are built around something like 55 × 40 × 20 cm, which totals 115 cm, but what matters is the sum—not a single exact dimension template.

Singapore Airlines carry-on weight limit

This is the rule most people feel in real life.

• Weight: 7 kg (15.4 lb) per carry-on piece

If you’re in a cabin that allows two carry-on pieces, that’s still 7 kg per piece, not one heavy bag plus one light one.

Singapore Airlines carry-on allowance by cabin class

Suites / First / Business

• Pieces: 2 carry-on pieces
• Weight: 7 kg per piece
• Size: 115 cm total dimensions per piece

Premium Economy / Economy

• Pieces: 1 carry-on piece
• Weight: 7 kg
• Size: 115 cm total dimensions

Singapore Airlines personal item rules (what you can carry in addition)

Singapore Airlines also allows one additional item on board (think handbag, laptop/notebook bag, document bag, small camera bag, etc.) in addition to your main carry-on allowance.

• Personal item size: Max 40 × 30 × 10 cm
• Important detail: If your “additional item” exceeds 80 cm total dimensions (L+W+H), it can be counted as part of your main carry-on allowance—meaning you may have to check one of the items.

Recommended Carry-On Bag for Singapore Airlines

The easiest way to avoid carry-on drama when you’re flying internationally is to use a bag that’s designed around international size limits, not U.S. domestic bins. That’s why I recommend the Travelpro Maxlite 5 International Expandable Carry-On Spinner (19″)—it’s compact, rolls well, and tends to be a safer fit across a wide range of international airlines.

If the airline you’re flying is known for strict sizing or weight checks, keep the bag unexpanded and avoid overstuffing exterior pockets so it stays as slim as it measures.

Why it fits Singapore Airlines’ size rule: Singapore Airlines limits each carry-on to 115 cm total dimensions (L+W+H). The Maxlite 5 International’s overall dimensions are 21.75″ × 15.75″ × 7.75″ (wheels/handles included), which converts to roughly 55.2 + 40.0 + 19.7 = 114.9 cm—so it aligns well with the 115 cm total-dimension cap.

One thing to watch on Singapore Airlines: the 7 kg carry-on weight limit can get tight if you pack heavy shoes, dense tech, or lots of liquids. If you’re close, shift heavy items into what you wear (jacket pockets) or keep your packing tighter and lighter overall.

It’s durable, reasonably priced, and holds enough for shorter trips (3-5 days). Plus the spinner wheels make it very easy to get through the airport quickly and effortlessly.

Carry-On Liquids: Singapore Airways Liquids Policy

Liquids are governed by security screening rules, and Singapore Airlines also publishes the standard restriction:

• Liquids, aerosols, gels: containers must be 100 ml (3.4 oz) or less (even if partially filled)
• Must be carried in one clear, resealable plastic bag with total volume not exceeding 1 liter
• One bag per passenger
• Remove the bag for screening when required

If your trip includes a U.S. departure, my TSA liquids rule guide is the simplest way to pack correctly without having security pull your toiletries.

Singapore Airlines Carry-On Pet Policy

Singapore Airlines does not allow pets in their cabins. 

If you are traveling with a pet, you will need to check them in as baggage to travel in the plane’s cargo. 

Singapore Airlines Carry-On Size & Fees

Singapore Airlines does not charge a fee for carry-on baggage that meets their size requirements.  If your bag is too large and doesn’t meet Singapore Airlines’ carry-on restrictions, you may be charged a fee to gate-check it.
