Total Weight: The sum of all item weights you entered, shown in both pounds and kilograms so you can cross-check against any airline's posted limit regardless of the unit they use.
Remaining Allowance: How much weight you can still add before hitting the airline's checked bag limit. A positive number means you are under; a negative number means you need to remove items.
Status: Green means under limit, amber means exactly at limit, and red means over. Most airlines charge $50–$200 per overweight bag, so catching an overage before you leave home saves real money.
How This Calculator Works
You name each item in your suitcase and enter its weight. The tool keeps a running total, converts between pounds and kilograms, and compares against your airline's weight limit. Switching the unit toggle converts all entered values on the fly. It assumes you are weighing items on a home scale — for best accuracy, use a luggage scale and include the empty suitcase weight as one of the items.
Quick Questions
What is the standard checked bag weight limit?
Most U.S. domestic airlines allow 50 lbs (23 kg) per checked bag in economy class. International flights often allow 50 lbs as well, though some carriers (especially in Europe and Asia) use 23 kg. Business and first class typically allow 70 lbs (32 kg).
Should I include the suitcase itself?
Yes. Airlines weigh the entire bag, not just its contents. A typical hard-shell checked suitcase weighs 8–12 lbs empty. Add it as an item to get an accurate total.
What happens if my bag is overweight at the airport?
Most airlines charge an overweight bag fee — typically $50–$100 for bags between 51–70 lbs, and $100–$200 for bags over 70 lbs. Some airlines refuse bags over 100 lbs entirely. Fees vary by airline and route.
What about carry-on weight limits?
Most U.S. airlines do not enforce carry-on weight limits, but many international carriers do — typically 15–22 lbs (7–10 kg). Check your specific airline's policy before traveling internationally.
