Frequently asked questions
How is the packed weight estimated?
Clothing items × 0.3 kg + shoe pairs × 0.8 kg + electronics items × 0.4 kg + toiletries (entered in kg) + empty bag weight (entered in kg) + a trip-type allowance. For the defaults, 7 × 0.3 + 2 × 0.8 + 3 × 0.4 + 1.0 + 2.5 = 8.4 kg.
What does the trip type add?
A flat amount: Business adds 0.5 kg, Winter / Ski adds 3 kg, and Beach Holiday, Backpacking and City Break add nothing. It is a single allowance for extra gear and does not change how clothing or shoes are counted.
Why 0.3 kg per clothing item?
It is an average built into the tool. Light tops weigh less and jeans, jackets and knitwear weigh more, so a single average can be off by kilograms on a bag of mixed clothes. If you know your heavy items, add them by treating each as two or three items, or reduce the count for light ones.
Are the allowance checks tied to an airline?
No. The tool compares the total with a fixed 23 kg checked limit and a fixed 10 kg carry-on limit. Airlines differ, so use the luggage weight calculator or the airline’s page to test your own limit once you have the estimate.
Can I plan more than one bag?
Run the tool once per bag and give each bag its own item counts and empty weight. The tool does not split items across bags automatically.
What is not included?
Books, gifts, bulky winter coats worn on the plane, laptops with chargers beyond the electronics count, food, medicine, camera gear, and anything bought on the trip are not modelled. Add their weight to the toiletries field if you want them counted.
How close is the estimate to a real scale?
It is only as good as the averages. The best use is early planning, before items are in the bag. Once packed, a luggage scale gives the figure the airline will see; compare it with the estimate to learn how your own packing differs from the averages.

How to use the packing weight calculator
Use this packing weight calculator to add up the total weight of your luggage contents and check it against airline weight limits. Add each item with its weight above, select your airline weight limit, and see instantly whether your bag is under, at, or over the limit. Free and works on any device.
How the packing weight calculator works
The packing weight calculator sums the individual weights of all items you enter and compares the total to your chosen baggage allowance. It highlights overweight scenarios and calculates excess weight so you know exactly what to remove. All calculations run locally in your browser — no data is uploaded.
How the total is built
The tool turns counts of items into kilograms using fixed averages, then adds the weights you enter yourself. Clothing counts at 0.3 kg each, a pair of shoes at 0.8 kg and an electronics item at 0.4 kg. Toiletries and the empty bag are typed in directly, and a trip-type allowance covers specialist gear. The total is then compared with a 23 kg checked and a 10 kg carry-on figure.
| Item | Weight | Notes |
|---|---|---|
| Clothing item | 0.3 kg each | Average, any garment |
| Pair of shoes | 0.8 kg per pair | Average |
| Electronics item | 0.4 kg each | Average |
| Toiletries | As entered | Entered in kg |
| Empty bag | As entered | Entered in kg |
| Business trip | +0.5 kg | Flat allowance |
| Winter / Ski trip | +3 kg | Flat allowance |
| Other trip types | +0 kg | Beach, backpacking, city break |
Worked examples
Each total was produced by running the calculator.
| List | Total | Checked room (23 kg) | Carry-on viable (10 kg) |
|---|---|---|---|
| 7 clothes, 2 shoes, 3 electronics, 1.0 kg toiletries, 2.5 kg bag, city break | 8.4 kg | 14.6 kg spare | Yes |
| 20 clothes, 3 shoes, 4 electronics, 1.5 kg toiletries, 3.5 kg bag, ski | 18.0 kg | 5.0 kg spare | No |
| 10 clothes, 1 shoe pair, 2 electronics, 0.5 kg toiletries, 1.2 kg bag, backpacking | 6.3 kg | 16.7 kg spare | Yes |
Where the estimate is most likely to be off
Shoes and bulky clothing dominate the error. In the ski example, 6.0 kg of the 18.0 kg is clothing, 2.4 kg is shoes and 3.0 kg is the trip allowance, so a single pair of ski boots or a heavy jacket can push the true weight well above the model. For a beach trip with light clothes the model may over-estimate. Keep a margin of a couple of kilograms either way.
Using the carry-on result
The carry-on line says Yes when the total is at or under 10 kg, which includes the weight of the empty bag. The backpacking list at 6.3 kg passes, and the city-break default at 8.4 kg passes, but neither considers bag dimensions, liquids rules or a separate limit on the airline you fly. Treat a Yes as a prompt to check your airline’s cabin rules.
Trimming a list
The breakdown shows which category to cut. Removing four clothing items saves 1.2 kg, one pair of shoes saves 0.8 kg and dropping one electronics item saves 0.4 kg. Choosing a lighter empty bag can save more than any of those, since the bag weight is typed in directly. Re-run the tool after each change to see the remaining margin. If you are packing for two people sharing a bag, add their items together and use the heavier of the two empty-bag weights. Remember to weigh anything you wear or carry separately on the plane, since the tool counts only what goes into the bag.
