Checked Baggage Size Limits: The 62-Inch Rule Explained

Checked baggage size limits are frequently misunderstood. Many travelers focus on weight — and rightly so, since overweight fees are significant — but size limits are enforced separately and can add $100–$200 to your checked bag cost if you exceed them. This guide explains exactly how checked bag size limits work, how to measure your luggage correctly, and what happens when bags are classified as oversized.

The 62 Linear Inch Rule

The near-universal standard for checked bag size is 62 linear inches, which equals 157 centimeters. This measurement combines all three dimensions of your bag:

Linear inches = Length + Width + Height

This is different from individual dimension limits. Airlines do not typically enforce a maximum on any single dimension for checked bags — only the combined total. A tall, thin bag and a short, wide bag can both fall within 62 inches even if they look very different.

Why Linear Inches, Not Individual Dimensions?

Checked bags go in the aircraft hold, where space is managed by weight and volume rather than exact shape. The combined linear dimension is a reasonable proxy for overall bulk without requiring carriers to specify every possible proportional combination. It also makes compliance easy to check at the counter with a tape measure.

Carry-on bags, by contrast, have individual dimension limits because overhead bins have specific width, depth, and height constraints that require consistent shapes.

Which Airlines Use the 62-Inch Rule?

This limit is consistent across US domestic carriers:

Airline	Size Limit	Weight Limit
American Airlines	62 linear in (157 cm)	23 kg (50 lb)
Delta Air Lines	62 linear in (157 cm)	23 kg (50 lb)
United Airlines	62 linear in (157 cm)	23 kg (50 lb)
Southwest Airlines	62 linear in (157 cm)	23 kg (50 lb)
Alaska Airlines	62 linear in (157 cm)	23 kg (50 lb)
Spirit Airlines	62 linear in (157 cm)	23 kg (50 lb)
Frontier Airlines	62 linear in (157 cm)	23 kg (50 lb)

The 62-inch / 157 cm standard has become the default precisely because uniformity makes compliance straightforward for travelers and staff alike.

European Airlines: Size Limits by Carrier

European carriers generally follow a similar principle, though they often express limits in centimeters and may specify the limit differently.

Ryanair

Ryanair's checked bag maximum is 81 cm × 119 cm × 119 cm — which totals 319 cm (126 linear inches). This is a very large limit; standard suitcases are nowhere near these dimensions. Ryanair's size enforcement focuses on weight (10 kg or 20 kg tiers) rather than physical dimensions.

easyJet

easyJet sets a hold bag maximum of 275 cm total (L+W+H combined) — equivalent to approximately 108 linear inches. Again, this is generous enough that nearly all standard luggage qualifies. easyJet's key constraints are weight-based (15 kg, 23 kg, or 26 kg options).

Wizz Air

Wizz Air allows checked bags up to 149 cm total (L+W+H), which is slightly under the US standard of 157 cm. Most large suitcases (29-inch) measure around 140–145 cm combined, so they still fit within Wizz Air's limit.

British Airways, Lufthansa, Air France

Full-service European carriers generally allow up to 90 cm × 75 cm × 43 cm, which totals 208 cm (82 linear inches) — larger than the US standard. The size limit on these carriers is rarely a concern; weight is the binding constraint.

What Counts as Oversized?

Any bag exceeding 62 linear inches (157 cm) on a US carrier is classified as oversized. The fee is charged in addition to the standard checked bag fee:

• American, Delta, United: $200 extra for oversized bags
• Southwest: $75–$125 extra for oversized bags
• Spirit, Frontier: $100 extra for oversized bags

A bag that is oversized and overweight pays both fees. A large 32 kg suitcase that exceeds 62 inches could face a $100 overweight fee plus a $200 oversized fee on top of the $35 standard bag fee — a total of $335 to check one bag each way.

Sports Equipment: Different Rules Apply

Sports equipment is typically exempt from the standard 62-inch size rule and is instead governed by sport-specific policies:

• Skis and ski boots: accepted as sporting equipment, usually $35–$75 per ski bag (containing skis, poles, and boots together)
• Golf clubs: typically $35–$75 per set in a golf bag or hard case
• Bicycles: usually $150–$200 per bike, requiring specific packing (pedals off, handlebars turned)
• Surfboards: varies widely, often $50–$150 per board
• Hockey equipment: often accepted at standard bag fee if within weight; oversized fees may apply

Check the specific airline's sporting equipment policy before flying, as rules and fees vary significantly.

Hard-Shell vs. Soft Bags: Size Implications

Hard-shell suitcases have fixed dimensions that do not change regardless of what is inside. If you buy a 30-inch hard-shell suitcase, its dimensions are fixed by the manufacturer and typically measure around 76 cm × 53 cm × 29 cm (158 cm combined) — just barely over the 157 cm limit.

Soft-sided bags compress. A bag nominally sized at 30 inches of height may compress to 62 linear inches when the contents are not at maximum volume. Airlines typically measure bags as presented; a compressed soft bag may pass where a rigid case of the same size would not.

Practical advice: if you own a 30-inch hard-shell suitcase, check the combined L+W+H on the manufacturer's specifications before flying. Many 30-inch cases are just at or over the 62-inch threshold.

How to Measure Your Checked Luggage Correctly

Measurement errors are common. Here is the accurate method:

Length: Lay the bag on its largest flat side. Measure the longest dimension (typically the tall axis when the bag is standing upright).

Width: Measure the next largest dimension — the front-to-back depth when the bag is standing.

Height: Stand the bag upright on its wheels. Measure from the bottom of the wheels to the top of the bag with the carry handle fully retracted (not extended). Do not include the carry handle when extended, as airlines measure with handles down.

Add the three measurements. If the total is 62 inches or under (157 cm or under), the bag is within standard limits.

Do not forget wheels and external pockets: On hard-shell cases, wheels typically add 3–5 cm to the height measurement when the bag is laid flat. Some airlines include wheels and handles in their measurement; others do not. When in doubt, measure including all protrusions to avoid surprises at check-in.

Luggage Sizes That Typically Fall Within 62 Inches

For reference, standard luggage sizes and their approximate linear inches:

• 20-inch carry-on: approximately 42–45 linear inches — well within the limit
• 24-inch medium checked bag: approximately 52–56 linear inches — well within the limit
• 26-inch large checked bag: approximately 56–60 linear inches — within the limit
• 28-inch large checked bag: approximately 60–64 linear inches — borderline; check specifications
• 30-inch extra-large checked bag: approximately 64–68 linear inches — likely oversized; verify before flying

Most travelers using standard 24-inch or 26-inch luggage are comfortably within the 62-inch limit and never encounter an oversized fee. The risk is primarily with extra-large (28-inch and above) hard-shell cases.
