Delta Bag Sizes and Fees: What the Numbers Mean

The suitcase is open on the floor and the question is simple: does this go in the cabin or does it get checked, and what does either choice cost? Delta’s own published figures answer most of that, but only if you read the sentences around the numbers. A tape measure alone will not settle it, because the measurement Delta uses is not the one most people take.

Delta counts a bag by adding length plus width plus height. That total is what the word linear means here, and it is why a bag that looks fine can still be over the limit. The airline also states plainly that the measurements include any handles or wheels, which is the sentence that decides whether a bag is refused at the gate. Everything on this page comes from Delta’s own published figures, each read from the airline’s page on a stated date. Fees and limits change, so treat every number as a snapshot rather than a permanent rule, and confirm the current figure with Delta before you fly.

Below is the table of Delta’s figures. After it, the sections walk through what each one actually means when you are standing over an open bag with a measuring tape.

What Delta Air Lines allows, and what it charges

What linear inches actually measure

Delta’s carry-on limit is a combined length plus width plus height of 45 linear inches, or 114 centimeters. The checked limit is 62 inches, or 157 centimeters, when you total length plus width plus height. Neither of those is the longest side of the bag. A bag can have a longest side well under the limit and still fail, because the limit is the sum of all three dimensions.

This is where most home measurements go wrong. People measure the height of the suitcase, see a number that looks reasonable, and stop. Delta is asking for a different sum. Take the tape around the bag in three directions, add the three numbers, and compare that total to the limit. A bag that is close on any one side is usually over on the total, because the three sides add up faster than people expect.

Delta also gives individual carry-on measurements: length, width and height may not exceed 22 by 14 by 9 inches, which is 56 by 35 by 23 centimeters respectively. That is a second test on top of the linear total. A bag can pass the linear sum and still fail if one side is too long, so both checks matter.

Why “including handles and wheels” decides the gate

Delta’s carry-on wording says the measurements include any handles or wheels. That single sentence is the difference between a bag that boards and a bag that gets pulled at the gate. Handles and wheels are part of the bag. They take up space. When you measure only the fabric body, you are measuring a smaller object than the one Delta will see.

A bag whose body measures within the limit can be over once the wheels and the extended handle are counted. The practical move is to measure the bag as it will actually sit in the sizer, wheels down, handle pushed in, straps and pockets as they will be when packed. If the total is close, the handles and wheels are usually what pushes it over.

The personal item is a separate allowance. Delta permits one personal item, and it must fit underneath the seat in front of you. That is a space test, not a tape-measure test, and it is the reason a personal item that looks small can still be too tall or too deep once it is full. A personal item is not a second carry-on, and it is not a checked bag. It is the one thing that goes under the seat.

Carry-on versus checked: which limit applies

The carry-on figures and the checked figures are different sizes, and mixing them up is common. The cabin limit is the smaller one: 45 linear inches, with individual sides capped at 22 by 14 by 9 inches. The checked limit is larger: 62 linear inches, or 157 centimeters, again as a total of length plus width plus height.

A bag that fails the carry-on test may still travel as a checked bag, provided it meets the checked limit and the weight rule. A bag that fails the checked limit is a different problem. Delta states that bags larger than 80 inches, or 203 centimeters, are not permitted at all. That is a refusal, not a fee. The same is true of weight: bags at 100 pounds, or 45.36 kilograms, or more are not permitted. Those two ceilings are hard stops, and no payment changes them.

Between the limits there are fees. Delta lists an oversize charge of $200 for bags from 63 to 80 inches, or 161 to 203 centimeters. That range sits above the standard checked limit and below the refusal point, which is why a bag can be both legal and expensive.

What happens when a checked bag is over the weight

Delta’s standard checked weight is 50 pounds, or 23 kilograms. Above that, the charges step up. A bag from 51 to 70 pounds, or 23 kilograms to 31.75 kilograms, carries a $100 charge. A bag from 71 to under 100 pounds, or 32 kilograms to 45.36 kilograms, carries a $200 charge. At 100 pounds or more, the bag is not permitted.

At the counter, a bag two pounds over the standard weight is not a moral failing and it is not a negotiation. It is a bag that falls into the next band, and the band has a price. The agent weighs it, the scale decides, and the charge is applied according to the published figure. The way to avoid it is to weigh the bag at home, on a bathroom scale, holding it while you stand on the scale and subtracting your own weight. That is the same measurement the counter will take, minus the calibration.

Weight and size are separate tests. A bag can be within the weight limit and over the size limit, or the reverse. Both are checked, and both can generate a charge.

The checked bag fees, in order

Delta’s first checked bag on a domestic itinerary is $45 each way. The second is $55 each way. Those are the two most common charges, and they are charged per direction, so a round trip doubles them.

Beyond the second bag, the figures jump. A third checked bag is $200. Bags four to ten are $200 each. Those numbers are not per trip in the same gentle way the first two are; they are the price of bringing a lot of luggage, and they are stated as flat figures. The oversize charge of $200 applies to bags from 63 to 80 inches, and the overweight charges of $100 and $200 apply to the two weight bands above the standard. A single bag can trigger more than one of these, which is how a heavy, large, third bag becomes an expensive object.

All of these are Delta’s own published figures, read on a stated date. They are not a prediction and they are not a promise. Fees change, routes differ, and the fare you bought may include an allowance that changes the math. Check the current figure for your own itinerary before you decide what to pack.

Measuring at home without guessing

Use a tape measure and take the three dimensions of the bag as it will travel: wheels down, handle in, pockets as packed. Add the three numbers. Compare the total to 45 linear inches for the cabin and 62 inches for checked. Check the individual carry-on sides against 22 by 14 by 9 inches. Weigh the packed bag.

If the carry-on total is close, move the heavy or bulky items to the personal item or to a checked bag. If the checked bag is close to 50 pounds, decide whether the $100 band is worth it or whether something comes out. If the bag is near 80 inches or near 100 pounds, the answer is not a fee; it is a refusal, and repacking is the only move.

The figures on this page are Delta’s, and they are time-bound. They describe what Delta published on the date they were read. They do not describe another airline, and they do not describe next year. Use them to measure the bag on your floor, then confirm with Delta before you fly.

Where these figures came from

Every figure above was read from Delta Air Lines’s own pages on the date beside it. Airlines change these without notice and without a changelog, so the date is part of the figure. The pages are linked here so the current wording can be checked directly rather than taken from this one.
