Flying Singapore Airlines? Learn SIA cabin luggage size, weight limits & smart packing tips to avoid surprises at the gate. From size restrictions to what counts as a personal item, here’s what every traveller should know before boarding. 

01 SIA Cabin Baggage Allowance by Class 

Depending on what class you are flying with SIA, your carry-on baggage would differ. 

Economy Class: 1 piece, up to 7kg

Premium Economy: 1 piece, up to 7kg

Business Class: 2 pieces, total combined weight up to 14kg

First Class & Suites: 2 pieces, total combined weight up to 14kg

Bear in mind that size matters as much as weight when it comes to SIA cabin luggage. Cabin crew may weigh your bags if they look bulky. So opt for simple carry-on forms and avoid odd-looking shapes for your cabin luggage. 

02 SIA Cabin Luggage Dimensions 

Singapore Airlines allows cabin luggage up to:

Max Size:

55cm x 40cm x 20cm (or 22in x 15in x 8in) – including handles and wheels.

To avoid issues, measure your cabin luggage or large carry-on items — some bags that look compact may exceed depth limits due to frame or handle design. 

03 Personal Items for Your SIA Cabin Luggage 

In addition to your main cabin bag, you’re allowed one small personal item. Examples include:

• A laptop bag
• A handbag or briefcase
• A camera bag
• A small backpack

Your item should be small enough to stow under the seat in front of you.

04 Common Mistakes to Avoid

Even experienced travellers can get caught out. Here are a few things to keep in mind:

• Overstuffing a cabin bag may push it past the 20cm depth limit.
• If your SIA cabin luggage looks oversized, it may be checked at the gate, even if it meets weight requirements.
• Wheels and side pockets count toward total dimensions — don’t overlook them when measuring.
• Flying with an external code-share partner? Baggage rules may differ, so always double-check if part of your trip is operated by another airline
  

05 Smart Tips for SIA Cabin Luggage Compliance 

• Opt for lightweight luggage to maximise packing while staying within the weight limit.
• Use compression packing cubes to organise and save space.
• If you’re flying Business or First, consider two smaller bags rather than one large one to balance the 7 kg-per-piece rule.
• Weigh your SIA cabin luggage at home with a portable luggage scale to avoid surprises.
• Choose luggage with minimal hardware or bulky wheels. These eat into the allowed size dimensions.

Bon Voyage! 

Whether you are travelling to a regional destination or flying long-haul, being aware of SIA cabin luggage size rules will help you travel lighter and faster. Understanding the limits, packing smart and choosing the right luggage means lesser time at check-in, smoother glides during transits and more time enjoying your journey!
