A polo has three lengths, not one, and which one settles the shirt depends on how the hem is cut. A straight hem gives you a front length and a back length. A curved or U cut hem gives you a front length, a back length and a side length at the seam, and the side is the one nobody checks and the one that decides whether the shirt looks right worn out. Front: the hem covers the belt and ends around the mid point of the fly. Back: it covers the seat when you bend to line up a putt and does not hang past the bottom of the seat when you are standing. Side, on a U cut hem: that seam is the shortest point on the whole hem, which is why a U cut polo that looks correct at the front is already shorter at the hip than a straight hem shirt would be.

This is the body of the shirt. The arm is the other dimension and it has its own landmarks, which is why how long a polo sleeve should be is a separate piece. Settle the hem first. The hem is what a dress code reads, what a belt fights with, and what turns a good shirt into laundry when it goes wrong.

The short answer

Check the hem shape before you check the length. A straight hem is judged at the front and the back. A U cut hem is judged at the front, the back and the side seam, and on a U cut hem the side seam is the one that decides whether the shirt reads clean untucked.

The hem shape, not the size label

start at the bottom of the shirt

Look at the bottom edge of the shirt before you look at anything else, because the hem shape tells you which landmark is actually in play. Two shirts in the same size, on the same body, will sit differently at the hip if one is cut straight and the other is cut curved. The tag cannot tell you that. The hem can.

A straight hem runs level across the front and level across the back, with the back usually cut a little longer so it stays put when you sit down. Proper Cloth, in its reference on how to achieve the perfect polo shirt fit, describes its Polo Hem as one that features “a straight front hem, as well as a straight back hem that is 1" longer”, and gives the worked example that “if your saved size features a 30" Shirt Back Length, your Polo Hem design shirt would measure 31" in the Shirt Back Length.” That is Proper Cloth's own made to measure specification, and it is the only hard number in this post. It belongs to them. It is not a PILLAR specification, and PILLAR does not publish garment lengths for any of its polos.

A curved hem, the U cut, does something else entirely. It drops at the center front and the center back and scoops upward toward the side seam, so the lowest points sit over the fly and over the seat while the highest point sits on your hip. Same shirt, three different distances from your shoulder to the hem depending on where you measure. That is the whole reason the question has three answers.

Three positions, not one measurement

front, side, back

Check the front for coverage, the back for the bend, and the side for how the shirt reads standing still. Landmarks beat numbers here, because a landmark travels with your body and a number on a size chart does not.

Front

The hem covers the belt and ends around the mid point of the fly. Higher than that and it climbs above the buckle the second you raise your arms, which is every swing you take. Lower and it stops reading as a polo and starts reading as a tee shirt.

Side

Only in play on a curved or U cut hem, where the side seam is the shortest point on the hem. This is where the shirt meets your hip and it is the edge people see when you are standing and talking. Get it right and the shirt looks finished worn out.

Back

It has to cover the seat when you bend to line up a putt or pick a ball out of the cup, and it cannot hang past the bottom of the seat when you are standing upright. Those two demands are what make back length the hardest of the three to buy.

The side seam, not the front hem

the u cut case

On a U cut hem the side seam is the shortest point, so the side seam is where you judge the shirt. The front hem on a U cut polo is a decoy. It will look long, because it is long, because it has to cover a belt and a fly that sit lower than your hip does. Judge the shirt there and you will talk yourself out of a hem that is cut correctly.

Move your eye to the seam. If the scoop lifts off your hip and clears it, the shirt reads intentional untucked, and the front and back panels still do their covering job. If the seam sits down on your hip with the front hem, the curve is too shallow to buy you anything and you are wearing a straight hem shirt with a decorative wiggle in it.

The PILLAR polos carded here are all cut with a U cut hem, which is the reason this article can be written at all. The David Polo and the Steven Polo are both classic athletic fit, both four way stretch, both sweat wicking, and both pre shrunk, so the hem you judge on the first wear is the hem you keep. If you want the broader argument about cut, what separates an athletic polo from a regular one sits next door.

on length

Every polo answers the length question three times. Most men only ever read the first answer.

The U cut hem is the reason this one works untucked without looking like you forgot. 84 percent nylon and 16 percent spandex, four way stretch, sweat wicking, classic athletic fit, firm collar. Pre shrunk, so the front landmark you check on day one holds after the wash. Navy is the shirt that goes anywhere a collar is asked for.

White is where hem length shows up worst, because the edge has nowhere to hide against a belt or a pair of trousers. Same build as the navy: 84 percent nylon, 16 percent spandex, four way stretch, sweat wicking, firm collar, U cut hem, pre shrunk. If the side seam is right on a white polo, it is right everywhere.

A length decision, not a style decision

tucked or untucked

Whether a polo can be worn out is decided by the hem before it is decided by the room. A shirt cut long enough to stay tucked through a full swing is usually too long to wear out, and a shirt cut to hang clean at the hip has less tail to hold in when you tuck it. You rarely get both in the same garment, and the ones that try tend to do neither well.

The outer limit is easy to test from behind. Effortless Gent, writing on how polo and short sleeve button up shirts should fit, notes that “Traditional polo shirts have a longer back hem compared to the front”, and sets the line at the back tail: “if the back tail is more than halfway down your butt, it's too long to be worn untucked.” That is their rule and their test, not a PILLAR measurement, and it is worth running in front of a mirror with your back turned before you decide a shirt is an untucked shirt.

Where and when you tuck is a different argument, and when a golf polo gets tucked in owns the etiquette by setting. This article owns the geometry. The two answers have to agree, and if the course says tucked and your hem says untucked, the hem loses and the shirt should have been a different shirt.

Where the hem is cut What to check Tucked Untucked
Straight front, straight back, level The front hem against the belt Holds, but the back can work loose when you sit Reads square and blocky at the hip
Straight front, longer straight back The back tail against the seat What it is built for, stays down through a swing Usually too long, the tail gives it away
Curved or U cut hem The side seam, the shortest point Works, the front and back panels are still there Best case, the scoop clears the hip
Deep curve with a long back tail How far the tail runs down the seat Very secure, built to stay in No, that tail was never meant to be seen

Brew is a print, and a print is exactly where a bad hem gets caught, because the pattern draws the eye straight to the edge. 88 percent polyester, 12 percent spandex, textured feel, four way stretch, sweat wicking, classic athletic fit. U cut hem and pre shrunk, which is why it holds the untucked read from the first tee to dinner.

Texas is the other pattern in the same build, for the man who wants the shirt to do a little talking without a logo doing it. 88 percent polyester, 12 percent spandex, textured feel, four way stretch, sweat wicking, athletic fit, U cut hem, pre shrunk. Tuck it if the clubhouse asks. It does not need you to.

Your torso, not your height

the part sizing charts miss

Hem length follows the torso, and the torso is not the same thing as the height printed next to the size. A shorter man carrying a long torso is the common case, and he will find that a shirt sized correctly through the chest arrives at his hip early, because the chart quietly assumed his height and his torso agreed with each other. They often do not. Check the landmarks on your own body and buy against those, then hand the rest of the question to finding a polo fit for your body type, which is where it belongs.

Slightly long, not slightly short

which way to miss

If you have to miss, miss long. Neither miss is really repairable, so this is about which failure you can live in. A polo that is too long cannot be fixed, because a knit hem is finished as it is made and a curved hem takes its side vents and its scoop down with it if anyone cuts into it. What you get back from a tailor is a different shirt, shorter and wrong in the shape.

A polo that is slightly short is worse to wear, though, which is the part men get backward. Slightly long sits a touch past the fly and reads relaxed. Slightly short lifts off the belt the moment you reach for anything overhead, refuses to stay tucked through a swing, and shows a band of shirt tail and skin at the back when you bend to your ball. One of those is a compromise. The other is a problem you notice on every hole.

The wash, not the rack

where a good hem goes wrong

A hem that moves in the wash undoes every landmark you just checked on the rack. Heat is what does it, and it takes the collar with it, which is the same mechanism behind why polo collars curl. Wash cool, skip the hot dryer, and a correct hem stays correct.

Pre shrunk is a published spec on both PILLAR polos, so the front landmark you check on the first wear is the one you keep. What PILLAR does not publish is a shrinkage percentage, and nobody here is going to invent one for you. Pre shrunk is the claim, a number is not, and any brand that gives you a tidy percentage for a knit is telling you more than it knows. The rest of the range sits in the men's polo collection if you want to compare hems across colors.

Questions, not guesses

the ones people actually type

Short answers, in the words people use to ask them.

How long should a polo be untucked?

Long enough to cover your belt at the front and your seat when you bend, short enough that the back tail does not run down past the bottom of your seat when you stand. Effortless Gent draws the outer line at the back tail running more than halfway down your backside, and that is their rule rather than a PILLAR measurement. On a curved or U cut hem, check the side seam too, because that seam is the shortest point on the hem and it is the edge people see at your hip.

Should a polo cover your belt?

Yes. The front hem should cover the belt and end around the mid point of the fly. A polo sitting on or above the buckle will climb the second you raise your arms, and it will not hold a tuck through a full swing either.

How do I know if my polo is too long?

Turn your back to a mirror and look at the tail. If it runs well down the seat, the shirt was built to be tucked and it will read as laundry worn out. At the front, a hem dropping toward the bottom of the fly reads as a tee shirt rather than a polo. Neither one improves after a wash.

Can a tailor shorten a polo that is too long?

Not well. A knit polo hem is finished as part of the garment, and on a curved hem the side vents and the scoop go with it, so cutting it down changes the shape of the shirt and not just the length. Buy the right length instead of planning to fix the wrong one.

How much does a PILLAR polo shrink in the wash?

PILLAR does not publish a shrinkage percentage, so there is no honest number to give you. What is published is that the David Polo and the Steven Polo are pre shrunk, which means the front landmark you check on the first wear is the one you keep. Wash cool and stay off high heat regardless, because heat is what moves a hem and a collar.

Does a U cut hem mean I cannot tuck the shirt?

You can tuck it. The front and back panels on a U cut hem are the long points, so there is shirt there to hold in. The point of the cut is that it does not force you to, because the side seam clears the hip cleanly enough to wear the shirt out.

Do tall men need a longer polo?

Length follows the torso, not the height. A tall man built long in the leg can need less shirt than a shorter man carrying a long torso, and the size chart will not tell either of them that. Check where the hem lands on your own body and buy against what you see.

Buy the hem, not just the shirt

The David Polo and the Steven Polo are both cut with a U cut hem and both come pre shrunk, which is the short version of a shirt that ends where it should and stays there.
