An airline baggage weight limit is the maximum weight allowed for each checked bag or carry-on before overweight fees apply. Limits vary widely by airline — from 15 kg on budget carriers to 32 kg on premium routes. Enter your bag weights below to instantly see if you are within limits and estimate any overweight charges.

How to Use the Luggage Weight Checker
Packing for a flight means balancing what you need against airline weight limits — and miscalculating costs real money. Most major airlines charge $50 to $200 or more for each bag that exceeds the weight limit. This free luggage weight checker lets you verify every bag before you reach the airport check-in desk, so you can redistribute weight or leave items behind rather than pay surprise fees.
Step 1: Select Your Airline
Choose your airline from the dropdown at the top. The tool includes checked bag and carry-on weight limits for ten major carriers: United, Delta, American, Southwest, Ryanair, easyJet, British Airways, Lufthansa, Emirates, and Singapore Airlines. If your airline is not listed, select "Custom limits" and enter the specific limits from your airline's website or booking confirmation. The information bar updates immediately to show the checked bag limit, carry-on limit, number of free bags, and an estimated overweight fee.
Step 2: Choose kg or lbs
Toggle between kilograms and pounds using the unit switcher. The baggage weight limit is displayed in the unit you select. Your bathroom scale may show stones or pounds while your airline quotes limits in kilograms — switching units here saves you the manual conversion. The tool handles the math: 23 kg equals 50.7 lbs, and 50 lbs equals 22.7 kg.
Step 3: Enter Your Bag Weights
The first bag entry appears automatically. Type your bag's weight in the input field and select whether it is a checked bag or a carry-on — each type is measured against the correct airline limit. Click "Add Another Bag" to check multiple pieces of luggage at once. You can add as many bags as you need and remove any entry with the trash icon. Results update in real time as you type.
Step 4: Read Your Results
The weight check summary shows each bag's status with a colour-coded progress bar. Green means the bag is within the limit; red means it is over. For overweight bags, the summary shows exactly how much over the limit the bag is and an estimated fee based on the airline's typical overweight charge. The total section shows your combined weight across all bags and the total estimated fees you could face at check-in. Use this information to redistribute items between bags or move heavy items into a lighter bag to avoid charges.

What happens if my bag is over the weight limit?
Airlines charge overweight baggage fees that typically range from $50 to $200 per overweight bag per flight. The fee depends on the airline and how much over the limit your bag is. Some airlines charge in tiers (e.g., 23-32 kg is one fee, 32+ kg is another). This tool provides fee estimates based on typical airline rates.
What is the standard checked bag weight limit?
Most major airlines allow checked bags up to 23 kg (50 lbs) in economy class. Some airlines like Southwest allow up to 50 lbs free, while premium carriers like Emirates allow 30-35 kg in business class. Always check your specific airline and ticket class before flying.
What is the carry-on weight limit for most airlines?
Carry-on weight limits vary significantly by airline. European budget carriers like Ryanair and EasyJet enforce strict 10 kg (22 lbs) limits. Most US airlines like Delta and United do not publish a specific weight limit for carry-ons but enforce size restrictions. Asian carriers often limit carry-ons to 7-10 kg.
How do I convert kilograms to pounds for my luggage?
To convert kilograms to pounds, multiply by 2.20462. For example, 23 kg equals approximately 50.7 lbs. To convert pounds to kilograms, divide by 2.20462. Our tool handles this conversion automatically when you switch between kg and lbs modes.

Does the airline data get updated?
The airline weight limits included in this tool reflect standard published economy class limits and are updated regularly. Airlines occasionally update their policies, so always verify the latest rules on your airline's official website before your flight, especially for premium cabin tickets or codeshare flights.
