Sometimes length and inseam are the same number. Frequently they are not, and the gap between them is about 30 cm, which is enough to order badly.
The confusion is real and it is not your fault. Two different industries settled on the same word for two different measurements, and neither has any intention of changing.
The short answer
On an American denim label, length means inseam. On a garment size chart from most of the rest of the world, length means the total outside length of the trouser, waistband to hem.
One includes the rise. The other does not. That is the entire disagreement.
The three lengths a pair of trousers has
| Name | Measured from | Typical adult figure |
|---|---|---|
| Inseam | Crotch join to hem, inside the leg | 70 to 86 cm |
| Outseam, or total length | Waistband to hem, outside the leg | 95 to 112 cm |
| Rise | Crotch join up to the waistband | 25 to 32 cm |
The rise is the difference between the first two. Add it to an inseam and you get an outseam.
What 32 x 34 actually means
The first number is the waist in inches. The second is the inseam in inches.
So a 32 x 34 is a 32 inch waist with a 34 inch inseam, which works out at roughly 81 cm and 86 cm. The total outside length of that trouser would be somewhere near 112 cm, and it appears nowhere on the label.
This system comes from workwear and denim, where the waist genuinely is close to the body measurement. It travels badly to elasticated or drawstring trousers, which is part of why so few brands outside denim use it.
When length does not mean inseam
Every Amaji product page carries the manufacturer's own flat measurement chart for that garment, transcribed and converted to centimetres. Across the 98 charts on the site, the word inseam does not appear once. All 22 charts covering bottoms report a column called length, and in every case that length is the outside measurement.
The Quick-Dry Cargo Joggers read 102 cm at S, 104 at M and 106 at L. The Cotton Linen Wide-Leg Pants read 102, 104 and 106 over the same sizes. Read as inseams those would be absurd. Read as outside lengths they are ordinary trousers.
A ten-second test for any size chart
Look at the number and ask whether a person could have a leg that long.
- Under 90 cm, or under 36 inches. Almost certainly an inseam.
- Over 95 cm, or over 38 inches. Almost certainly an outside length.
- Between 90 and 95 cm. Check the chart's other columns. If it lists a rise, the length is probably an inseam.
On shorts the same test works in miniature. A 45 cm figure is an outside length. A 45 cm inseam would be a trouser.
Which one should you shop on?
Whichever one you can measure on a pair you already own and like.
That is the honest answer. Comparing a garment against a garment is far more reliable than comparing a body measurement against a chart, because it removes every assumption about rise, fabric drop and where the brand thinks a hem should sit.
Lay out your best-fitting trousers, measure both figures once, and write them down. From then on you can read any chart in either convention.
A worked example
Say your favourite trousers have an 80 cm inseam and a 106 cm outside length. The difference of 26 cm is the rise, and it tells you those are a fairly standard mid-rise cut.
Now you meet a chart quoting 104 cm at M with no inseam anywhere. Subtract your 26 cm rise and you get an estimated 78 cm inseam, about 2 cm shorter than what you own. On most cuts that is close enough to be inside the tolerance.
Hand measurement varies by 2 cm to 3 cm on any single figure, so two sizes within 3 cm of each other are effectively the same length. Our how we measure page explains where each figure comes from and how much room to leave.
A rough inseam by height
If you have nothing to measure against, height gives you a starting point. As a rule of thumb an adult inseam lands near 46 per cent of total height, before any allowance for how you like the hem to break.
| Height | Starting inseam | Outside length, mid rise |
|---|---|---|
| 165 cm / 5 ft 5 in | 76 cm / 30 in | about 102 cm |
| 170 cm / 5 ft 7 in | 79 cm / 31 in | about 105 cm |
| 175 cm / 5 ft 9 in | 81 cm / 32 in | about 107 cm |
| 180 cm / 5 ft 11 in | 84 cm / 33 in | about 110 cm |
| 185 cm / 6 ft 1 in | 86 cm / 34 in | about 112 cm |
Treat these as an opening bid. Leg length varies a great deal between two people of the same height, and a trouser meant to sit high will always read shorter in the inseam than one cut to sit on the hip.
The outside lengths in the last column assume a 26 cm rise. A dropped or pleated cut adds to it, which is why the dropped-rise cuts can carry a much larger total length on the same leg.
Why brands will not simply publish both
Charts are built from whatever the factory measured, and factories measure to the convention of their own market. A brand reprinting a supplier chart inherits that convention along with the numbers.
The fix is not to wait for the industry to agree. It is to know your own two figures, and read every chart through them.
Where to go next
To find and measure the seam itself, read where the inseam is on pants. For the outside of the leg, see what an outseam measurement means and how to measure it. If a pair is right in the waist and wrong in the leg, the cost of hemming pants is the next question. Shop pants.
