The Parts of a T Shirt: A Quick Overview
Every t shirt is built from the same handful of pieces, and small differences in each piece separate a shirt that holds its shape from one that twists and stretches. Learning the parts of a t shirt gives you the words to brief a factory, to compare samples and to explain exactly what you like or dislike about a reference garment.
The basic pieces are the body, which is the front and back panels, the sleeves, the neckband or collar, the shoulder seams, the side seams and the hem. Some shirts add a pocket, a taped neck seam or a printed label in place of a sewn one. Each piece is cut from knit fabric, usually single jersey, and joined with stretch stitches.
Garment anatomy sits inside a wider specification, described in our guide to how to design a t shirt for production.
Body, Shoulders and Side Seams
The body is made from a front panel and a back panel. They are joined at the shoulders and along the sides. The shoulder seam is often reinforced with a strip of tape, called shoulder-to-shoulder tape, that stops the seam stretching under the weight of the garment. Without it, shoulders can sag over time.
Side seams join the front and back under the arm. Some shirts are made as a tube of knit fabric with no side seams, which is called tubular construction, and it can reduce twist but limits how much the shape can be graded. Most shirts made in volume have side seams, which allow a closer shape and more control over fit.
Body width, body length and shoulder width are the measurements that decide the fit, and they are listed in the garment points of measure guide. Oversized and boxy shapes change these proportions, and our guide to boxy t shirt manufacturing covers them.
Sleeves, Armholes and Sleeve Hems
Most t shirts use a set-in sleeve, in which the sleeve cap is sewn into a shaped armhole. A raglan sleeve, common on baseball-style shirts, has a seam that runs from the neck to the underarm, and a drop shoulder sleeve is joined low on the arm for a relaxed look. The sleeve type changes the pattern and the way the shirt hangs, and it is explained in the types of sleeves guide.
The sleeve hem is the finished edge at the end of the sleeve. It is usually turned and stitched with a coverstitch, which gives a neat double line on the outside and a stretchy finish. Sleeve length, sleeve opening width and the hem finish all belong in the specification.
The Neck: Ribbed Band, Self-Fabric Band and Tape
The neck is the most visible of all the parts of a t shirt, and it gets the most attention, because it frames the face and shows wear first. Two builds are common. A ribbed neckband uses a strip of rib knit, which stretches over the head and recovers. A self-fabric band uses the same jersey as the body, folded and stitched, which gives a flatter, more modern look but needs careful fabric choice to hold its shape.
Inside the neck, a strip of tape covers the seam between the neckband and the body. This neck tape stabilises the seam, adds comfort and gives a place to print a brand label instead of sewing one in. Neck width, neck drop at the front, band width and band fabric are the measurements to specify.
Neck construction options
| Build | How it is made | Look and feel | Watch for |
|---|---|---|---|
| Rib neckband | Stretch rib knit sewn around the neckline | Classic, recovers well | Rib quality and recovery |
| Self-fabric band | Same jersey folded into a band | Flat, clean line | Can stretch if the fabric is soft |
| Taped neck seam | Tape covers the inside neck seam | Neat inside, supports the seam | Tape width and softness |
| Printed neck label | Brand and size printed on the neck tape | Tagless comfort | Print durability |
A general comparison. Final choices depend on fabric weight and your target look.
Rib Neckband vs Self-Fabric Band
The choice between a rib neckband and a self-fabric band is one of the first decisions in the parts of a t shirt. A rib band has built-in stretch and recovery, which helps the neck go over the head and return to shape. A self-fabric band is a cleaner, flatter look, but it relies on the jersey holding its shape, so it suits heavier fabric and a tighter, more controlled neck.
Rib neckband vs self-fabric neckband
Rib neckband
- Rib stretches and recovers well
- Familiar, classic look
- More forgiving on lighter jersey
Self-fabric band
- Rib can show wear or ripple at the seam
- Needs a separate rib fabric to be sourced
- Rib colour must match the body
A general comparison. Final choice depends on fabric weight, target look and cost, and should be approved on a washed sample.
Neckline Types: Crew, V, Scoop, Henley and Boat
The neckline is the shape of the opening at the front. The crew neck is round and close to the base of the neck, and it is the default for most tees. A V neck dips to a point at the chest. A scoop neck is a wider, deeper curve, a henley adds a short button placket below a round neck, and a boat neck is wide and shallow, running across the collarbones.
Each neckline needs its own measurements, and the numbers that matter are the neck width at the shoulder seams and the front drop from the shoulder seam to the lowest point. A change of a few millimetres in either measurement changes how the shirt sits, so approve a sample on a person or a fit model before bulk.
Neckline types compared
| Neckline | Shape | Typical use | Spec points |
|---|---|---|---|
| Crew | Round, close to the base of the neck | Everyday and printed tees | Neck width, front drop, band width |
| V neck | Dips to a point at the chest | Layering and a sharper look | V depth, angle, finishing at the point |
| Scoop | Wider, deeper curve | Womenswear and relaxed shapes | Width, depth, band or binding |
| Henley | Round neck with a short button placket | Casual shirts with detail | Placket length, buttons, stitching |
| Boat | Wide, shallow, across the collarbones | Fashion and breton styles | Width, drop, shoulder stability |
A general guide. Naming varies slightly between brands, so approve the shape on a sample.
The Hem, Sleeve Cuffs and Other Details
The bottom hem is turned and stitched, usually with a coverstitch. A straight hem is common, while a curved or split hem, with a small vent at each side, gives a streetwear look. The hem width and the depth of the turn are specification points because they change how the shirt falls.
Other details that change the parts of a t shirt include a chest pocket, a ribbed cuff on a long-sleeve shirt, an extra panel in a colour block, and a printed or embroidered label. Each detail adds a step to production and a point of possible variation, so include only the ones you need. Our guide to hem types and seam finishes explains the finishing options.

A count of components in the basic tee described on this page: four jersey panels (front, back, two sleeves), one neck rib or band and two tape or label pieces (neck tape and a label). A teaching example, not an industry average.
Fabric Choices That Change How the Parts Behave
The same pattern behaves very differently in different fabrics. A heavier jersey gives a structured neck and body, while a lighter fabric drapes and may twist. The yarn, whether combed, carded or ring spun, changes the surface and the way the neck holds its shape. Our guide to ring spun vs combed cotton t shirt fabric covers those choices, and the guide to fabric GSM for t shirts and hoodies covers weight.

Spec Checklist for the Parts of a T Shirt
A short specification written part by part makes a sample much more likely to match your intent first time. Use the checklist below as a starting list, and add measurements from your size chart. Standards such as those from ISO can help define test and size terms.

Common T Shirt Problems and the Part to Blame
Most complaints about a t shirt trace to one of the parts of a t shirt. A wavy neck is usually caused by a neckband cut too long or a stretchy fabric with no tape. Twisting side seams often come from fabric that was not stabilised before cutting. Shoulders that sag or ride forward point to missing tape or poor shoulder seam placement.
The quickest way to prevent these problems is to approve a sample washed to your care instructions, not only a new one. Testing is covered in the garment testing guide, and fit comments on a sample are explained in the fit session guide.
How Ruhrose Approaches Tee Anatomy and Neck Details
Ruhrose develops hoodies, fleece, jersey, denim and woven casualwear with production in Bangladesh and UK buyer support. For tees and other jersey styles, we confirm fabric, neck construction and measurements with you before sampling and approve a washed sample before bulk. We do not publish prices or minimums here, because they depend on weight and quantity. The AATCC publishes test methods for textiles if you want to understand how performance is measured.
