Right here’s a state of affairs you don’t wish to be in: you roll as much as the airplane gate they usually ask you to see in case your carry-on suits within the measuring field. No downside. You carry your suitcase, put it in, and… oops… it doesn’t match. You flip it over, attempt to shove it in, bounce on prime of it. There’s no approach it’s stepping into.
“Sorry,” says the gate agent. “You’re going to should examine that bag, and also you’re going to should pay for it.”
Happily, you don’t ever should be in that scenario. With just a bit forethought, it’s straightforward to lookup your airline’s measurement restrict and measure your suitcase to make sure it should match.
And belief me, it’s significantly better to learn to measure baggage forward of time so that you don’t should pay to examine a bag you weren’t planning on paying for.
So, if you wish to know the way to measure your baggage, you’re in the best place. Let’s get began.
What You’ll Must Measure Baggage
Measuring baggage is definitely fairly simple, however you’re going to want one thing to measure with (loopy, I do know). A tape measure is the best choice, however a yardstick may even do the trick.
And hey, if all you’ve got is a dinky six-inch Care Bear ruler, you can also make do with that. Keep in mind the trick of measuring six inches, marking the spot together with your finger, and measuring once more from there? It’s not actual, however it’ll do the job.
Along with some kind of measuring system, it’s useful to measure in an space with a laborious ground subsequent to a wall (we’ll get into this later).
I additionally advocate utilizing a guide, clipboard, or another flat floor to ensure you get an correct measurement.
If you wish to weigh your baggage (which is a good concept), you’ll additionally want some kind of scale. A standard toilet scale works properly, however a luggage scale is affordable, compact, and simpler to make use of. For those who journey quite a bit, it may be factor to have.
If you wish to get actually fancy, Samsonite has a two-in-one tape measure/luggage scale combo. It’s fairly nerdy, however I’ll admit that I need one.
How To Discover Airline Measurement Restrictions

The very first thing it’s essential to do is locate the baggage measurement and weight restrictions for carry-on and checked baggage for the airline(s) you’ll be flying with. That’s as straightforward as Googling “[fill in your airline] baggage measurement restrictions.”
For instance, if I Google “Frontier baggage measurement restrictions” the primary result’s a handy FAQ web page that reveals Frontier’s size and weight limits.
It’s additionally useful to grasp the several types of baggage you might be allowed to carry. Most airways permit every passenger one private merchandise, one carry-on bag, and a number of checked baggage.
Private Merchandise: 18″ x 14″ x 8″
Your private merchandise is a small bag or purse that may match below the seat in entrance of you. I like utilizing a private merchandise to maintain electronics, books, snacks, and the rest I need shut at hand whereas flying.
Private merchandise measurement limits will differ by airline, however the most typical measurement is eighteen inches excessive, 14 inches large, and eight inches deep.
In fact, in the event you carry a private merchandise carry-on that’s the max measurement, meaning you gained’t have any area to stretch out your ft.
Carry-On Baggage: 22″ x 14″ x 9″
Carry-on luggage will match within the overhead bin on the airplane, so the precise baggage measurements are fairly necessary. In case your bag is just too huge, it simply gained’t match, and there’s not a whole lot of wiggle room. With carry-on baggage, it’s much more necessary to measure baggage exactly.
Carry-on measurement limits differ from one airline to the subsequent, however the usual restrict is 22 inches tall, 14 inches lengthy, and 9 inches deep.
It’s necessary to notice that carry-on limits for baggage for worldwide journey are a bit totally different, with the usual carry-on baggage measurements for many worldwide airways being 21.5 inches x 15.5 inches x 9 inches.
Checked Baggage: 62 Linear Inches
Checked baggage is measured a little bit otherwise from carry-on baggage. As an alternative of getting most limits for the peak, width, and depth, airline checked baggage measurement limits use what they name “linear inches,” which simply means including the general dimensions collectively.
Most airways restrict checked baggage to 62 linear inches (157 cm). Fortunately, this covers most checked luggage you should purchase, which is able to include a peak of anyplace from 26″ to 30″. The opposite dimensions are a mix of the inches remaining.
How To Measure the Peak, Width, and Depth

Whenever you’re able to measure baggage measurement, the primary info you’ll wish to get is the peak, width, and depth of your suitcase. These three numbers are an important baggage measurements you’ll use to see in case your baggage will match.
Step 1: Absolutely Pack Your Suitcase
I like to recommend measuring baggage after it’s absolutely packed (as full as you’ll have it in your journey. You wish to be as correct as potential, and having a completely packed bag means you’ll be measuring baggage that would be the similar measurement once you head to the airport.
That is particularly necessary for measuring versatile softside baggage and duffel baggage. These extra versatile baggage can flex, bulge, and develop considerably when you’ve got them absolutely packed, so that you wish to ensure you know the true most measurement.
Step 2: Set the Suitcase By a Wall
Ideally, you’ll discover an space in your house that has a tough ground floor subsequent to a wall. Wheels depend in complete baggage measurement, they usually’ll sink into carpet, which means you gained’t get an correct measurement. Onerous flooring are the place to be.
Set your suitcase upright on its wheels, and again it up subsequent to the wall. This provides you with one thing straight to measure towards.
Step 3: Use a E-book and Measuring Tape to Measure the peak
We’re lastly to the half you’ve been ready for: truly the way to measure baggage measurement. That is the place you’ll must seize your tape measure (or yardstick) and a guide.
The best approach I’ve discovered to precisely measure the peak of your suitcase is to position a guide on prime of the tallest level (together with the handles) and maintain it degree (doesn’t should be tremendous exact, simply ensure that it appears to be like flat).
To measure duffel baggage, ensure you don’t push down too laborious on the guide, as that may squish your bag and provide you with an inaccurate baggage measurement.
When you’ve acquired the guide on prime, you need to use your tape measure or yardstick to measure the gap from the ground to the guide. Utilizing the guide means you don’t should eyeball a measurement from out to the aspect and might get a extra correct quantity.
Step 4: Flip and Repeat for Width and Depth
When you’ve measured the peak, flip your bag onto its aspect, and use the guide and tape measure technique once more to measure from the ground to the best level. This would be the width.
Then, flip your suitcase flat on its again. Use the identical technique one final time to measure from the bottom to the best level. This would be the depth.
Avoiding Confusion With Peak, Width, and Depth
Some airways will use totally different phrases than peak, width, and depth. Some might name the width the size. Some might name the depth the width. Some might name the peak the size.
Ultimately, it doesn’t matter. Simply take a look at the numbers and ensure your suitcase dimensions are smaller than the airline restriction dimensions.
For instance, if an airline says you want a bag that’s smaller than 24 inches lengthy, 10 inches large, and 16 inches tall, you’ll be completely superb in case your bag measures 22 inches tall, 16 inches large, and 10 inches deep.
When unsure, ignore the phrases and take a look at the numbers.
How To Calculate Linear Inches (for Checked Baggage)
Whenever you’re determining the way to measure baggage, you might come throughout the time period linear inches in an airline’s measurement restrict. This can be a distinction in the way in which airways measure baggage between checked baggage and carry-ons. Carry-ons shall be measured by the three dimensions, when you measure checked baggage with linear inches.
Basically, linear inches simply means you’re taking the peak, width, and depth you measured earlier, after which add them collectively.
Yep, that’s it.
Right here’s a fast instance: say I measured my checked bag and located it’s 24 inches tall, 18 inches large, and 10 inches deep. I’d then add these collectively: 24 + 18 + 10 = 52. So I now know that my checked bag is 52 linear inches.
It could seem to be a bizarre strategy to measure baggage, however linear dimensions provide you with extra flexibility within the form of your baggage. An extended, skinny bag and a brief, fats bag can each match inside the restrictions.
How To Weigh Baggage

Not solely do it’s essential to ensure that your suitcases match inside baggage measurement limits; you additionally must examine weight restrictions. Having a bag that’s over the utmost weight can result in further checked baggage charges or being compelled to examine your carry-on (additionally costly). That’s why it’s necessary to determine what your bag weighs forward of time.
Once more, step one is to determine what the burden restrict is. The best approach is simply to Google “[fill in your airline] baggage weight limits.”
Typical limits are 50 lbs for checked baggage, and anyplace from 15 to 35 lbs for carry-on baggage.
As soon as you understand the burden restrict, you may weigh your suitcase (absolutely packed, after all), to see if it suits.
Baggage Scale
The best strategy to examine in case your bag is below the burden restrict is to make use of a baggage scale. These easy units have a hook that goes by means of your suitcase deal with.
Lavatory Scale
For those who don’t have a baggage scale, a traditional toilet scale works simply superb for measuring baggage weight.
Most definitely, you’ll simply have the ability to set your suitcase on the size (in all probability sideways) and browse the burden.
In case your suitcase gained’t match on the size (or covers up the numbers) you need to use this previous trick:
- Step on the size to measure your personal weight (write this down).
- Decide up the suitcase and step on the size once more to get the mixed weight (write this down).
- Do some math: (mixed weight) – (your weight) = (baggage weight)
What If My Bag Is Too Massive (or Too Heavy)?

Okay, let’s say you’ve gone by means of the entire course of to measure baggage dimensions, weigh baggage, and examine the airline measurement and weight limits, however now you’ve acquired an issue: your bag is just too huge or weighs an excessive amount of.
You continue to have a couple of choices, and it’s going to depend upon whether or not your oversize/obese baggage is a carry-on or checked bag.
Carry-On Baggage
Let’s begin with the state of affairs the place your carry-on suitcase is just too huge in a number of dimensions. Airways will often have a measuring field on the gate to ensure your bag is sufficiently small, so if it suits within the field, you’re good.
That’s excellent news when you’ve got a softside carry-on that’s simply barely too huge, since you would possibly have the ability to squish it in to suit. Do that at house to see in the event you can squish it down sufficient to suit the restrict.
If in case you have a hardshell bag that’s too huge (or a softside that’s greater than a bit over the dimensions restrict), you’re in all probability out of luck. In fact, it would probably not make sense to exit and purchase a brand new carry-on except you’re going to be flying often with this airline.
Usually, your possibility for outsized cabin baggage will simply be to examine them in. This does add some price to your journey. I typically wouldn’t advocate attempting to simply slip aboard with a carry-on that’s oversize. In the event that they determine it’s too huge, you’ll should examine it on the gate, which will be much more costly. Plus, it may not even match within the overhead compartments.
For obese baggage, you’ve got a couple of extra choices. The very best resolution is to divide the burden between different baggage or baggage. If in case you have a checked suitcase, transfer some stuff over to that. You too can carry an additional private merchandise to suit below the seat in entrance of you. Take a few of the heaviest gadgets out of your carry-on, and put them in your private merchandise till you’re below the burden restrict.
Checked Baggage
With checked baggage, oversize and obese baggage are typically nonetheless allowed, you’ll simply should pay extra. For baggage over the burden restrict, you may attempt the identical trick of transferring some weight into your carry-on or private merchandise.
