Specification for T-Shirt Necklines

T‑shirts seem like simple garments, but small details such as the neckline dramatically influence fit, style and printability. When choosing or designing a shirt for direct‑to‑film (DTF) printing, it helps to understand the common neckline types, how they’re sized and how each shape affects your design area. This guide outlines the key specifications behind popular necklines and shows how Printphase’s flexible DTF transfers can bring your ideas to life.

Why neckline specifications matter

• Fit and comfort: The neck opening must be large enough to pass over the head while still providing the desired look. A general rule of thumb from garment design books is that a close‑fitting crew or turtleneck can be approximated as one‑third of the shoulder‑to‑shoulder width. To ensure the shirt can be pulled on comfortably, the opening should stretch to at least 13.5 inches (women) or 14.5 inches (men) based on head circumference.
• Measurements: Professional spec sheets list the neck width and depth. In a regular‑fit T‑shirt size chart, the round (crew) neckline width ranges from 15.5 cm to 17.5 cm and the depth is 6.5–8 cm, while a V‑neck width is 15–16 cm with a depth of 12–14 cm. These numbers help pattern makers keep the neckline proportionate across sizes.
• Print area: Necklines with higher collars provide a larger uninterrupted canvas for graphics. Lower or plunging cuts reduce available print space and often require the artwork to be placed lower on the shirt.
• Style: Different cuts convey different aesthetics; choosing the right neckline helps your design appeal to the target audience. Whether you want a classic look for corporate uniforms or a fashion‑forward style for retail apparel, the neckline sets the tone.

Common T‑shirt necklines and their specifications

Crew neck
A crew neck is the classic T‑shirt collar: a round, close‑fitting neckline that sits high on the neck. It is one of the most popular styles and works for almost any body type. Women’s crew‑neck shirts often have slightly shorter sleeves, but the neckline shape remains the same.

• Shape and depth: The collar is usually finished with a rib band. For regular‑fit shirts the neck width is 15.5–17.5 cm, and the depth is 6.5–8 cm.
• Style and history: Crew necks date back to early sailors’ undershirts. They became a symbol of effortless cool when actors like Marlon Brando and James Dean wore them. The balanced, clean look flatters most face shapes.
• Printing considerations: This high neckline provides the largest uninterrupted print area; designs can be positioned higher on the chest without distortion. If you’re planning a bold graphic or logo, a crew neck is ideal.
• Printphase tip: Use our premium DTF heat transfers to achieve full‑color graphics on crew‑neck shirts. Our transfers adhere well and can be peeled hot, warm or cold at various temperatures.
  

V‑neck
A V‑neck features a V‑shaped cut that can range from shallow to deep. It’s popular for adding a fashionable, slimming effect; the plunging shape draws the eye downward, elongating the neck.

• Measurements: A regular V‑neck has a neck width of 15–16 cm and a depth of 12–14 cm. The deeper the V, the more pronounced the effect.
• Style: V‑neck shirts became popular in the 1970s and 80s. They suit both men and women and can look casual or dressy depending on the depth of the cut.
• Printing considerations: Because the V shape reduces the chest area, designs should be placed lower or scaled down to avoid being cut off at the neckline. Vertical or centered graphics work well.
• Printphase tip: To maximize print space on V‑necks, you can gang multiple designs on a single transfer sheet. Our gang sheet design tool lets you arrange artwork efficiently and position it where it works best.

Scoop neck and deep scoop

A scoop neck is a deeper, rounded neckline that sits lower than the crew neck. The deep scoop takes this cut further, creating a more daring, open look.

• Style: Scoop necks are relaxed and comfortable. They became popular in the early 2000s as a modern alternative to the crew neck. The cut keeps the wearer cool and is favoured in casual or athleisure outfits.
• Printing considerations: Like V‑necks, scoop necks limit the space above the neckline, so place graphics slightly lower.
• Printphase tip: If you’re printing on a scoop‑neck shirt from our blank apparel collection, choose vertical designs or centre your artwork lower on the chest. Our DTF transfers adhere to cotton, polyester and blends, so you can decorate any style.

Deep V‑neck

The deep V‑neck plunges far below the standard V. It’s popular for fashion‑forward looks and can accentuate jewelry or layered outfits. The depth varies by brand; some cuts nearly reach the hem. When designing for deep V‑necks, consider placing your print much lower on the garment or using smaller motifs.

Boat/Bateau neck

The boat neck (or bateau) has a wide, horizontal cut that runs along the collarbone. This elegant style reveals the shoulders and evokes mid‑century Parisian chic.

• Style: Boat necks are often used in women’s shirts but can work for unisex designs. They flatter narrow shoulders and create a balanced silhouette.
• Printing considerations: Because the neckline is wide and high, there’s still good space for prints, but minimalist or vertical designs complement the sophisticated aesthetic.
• Printphase tip: When printing on boat‑neck styles, our screen print transfers or DTF size prints allow you to place smaller graphics exactly where you need them without overwhelming the neckline.

Henley

A Henley T‑shirt features a buttoned placket at the neckline and no collar. Originally worn by rowers in Henley‑on‑Thames, it blends the rugged look of a polo with the comfort of a tee.

• Style: The buttoned design adds versatility—leave it unbuttoned for a casual look or button it up for structure. It suits men’s and women’s fashion and works well as a layering piece.
• Printing considerations: The placket reduces the central print area. Avoid placing designs over the buttons; instead, position graphics to the side or below the placket.
• Printphase tip: For Henley shirts, consider using our DTF roll sheets to produce transfers of varying sizes. You can cut individual designs and place them creatively around the placket.

Roll neck (mock/turtleneck)

While not always used for casual tees, roll necks (also called turtlenecks or mock necks) feature a taller collar that folds or “rolls” down. Designers use them for warmth and to frame the face. A high back neck helps keep the garment from shifting. When printing on roll‑neck shirts, place graphics lower on the torso to avoid the high collar.

Design and printing considerations

Choosing the right neckline isn’t just about aesthetics—it affects how your design will appear and how comfortable the shirt feels.

Balance style and print area

Vistaprint’s design guide recommends evaluating how the neckline frames your artwork: crew necks offer the most room for large, bold prints; V‑necks and scoop necks require smaller or lower‑placed graphics. Boat necks suit minimalist or vertically oriented designs. When designing for events or promotional wear, crew necks are versatile, but if you want a more fashion‑forward look, consider V‑necks, scoop or boat necks.

Comfort and audience

The neckline also influences comfort: crew necks sit snugly, while V‑necks and scoop necks offer a more open, ventilated feel. Think about your audience - Gen Z may prefer relaxed cuts, whereas corporate uniforms often use crew necks.

Proportion and fit

Use measurement charts to keep the neckline proportional across sizes. The Online Clothing Study table shows that round‑neck widths increase by about 0.5 cm per size and the depth grows from 6.5 cm to 8 cm. For V‑necks, maintain a consistent width and adjust depth slightly to keep the V visually balanced.

When drafting patterns from scratch, the neck width at the shoulders can be approximated as one‑third of the shoulder width. Ensure the neck opening can stretch to pass over the head: using knit ribbing allows about 50 % stretch, so a woman’s garment needs at least 13.5 inches of opening (20 in head circumference / 1.5) and a man’s garment 14.5 inches.

Frequently Asked Questions (FAQ)

What are the typical measurements for crew‑neck and V‑neck T‑shirts?
A measurement chart for regular‑fit T‑shirts shows that round (crew) necklines have a width of 15.5–17.5 cm and a depth of 6.5–8 cm, while V‑necks are similar in width (15–16 cm) but have a deeper 12–14 cm drop. These numbers increase slightly with larger sizes.

Which neckline is best for large prints?
For maximum print area, choose a crew neck. Vistaprint’s guide notes that the crew neck’s high, round collar provides a large, uninterrupted surface for bold graphics and allows the design to be placed higher on the chest. V‑necks and scoop necks offer less room near the neckline and are better suited to smaller or vertically oriented designs.

Can Printphase DTF transfers be applied to any neckline?
Yes. Printphase DTF transfers are engineered to adhere to cotton, polyester, blends and specialty fabrics at temperatures as low as 240–300 °F. They can be peeled hot, warm or cold, giving you flexibility when printing on scoop necks, deep V‑necks or boat necks. Just adjust the placement of your design to suit the neckline.

How do I choose the right neckline for my design?
Consider your design’s size and vibe. Crew necks suit bold logos, while V‑necks and scoop necks complement fashion‑forward or relaxed looks. Think about the wearer: a snug crew neck provides structure; open necklines offer ventilation and are popular among younger audiences. Also consider the occasion - corporate uniforms often use crew necks, whereas boat necks or Henleys can make casual apparel feel more elevated.

How do I place graphics on V‑neck or scoop‑neck shirts?
Because the neckline dips lower, position your design lower on the chest or choose smaller motifs so that the artwork isn’t cut off. Vertical designs can work well. Use our design & order gang sheet tool to experiment with placement before ordering your transfers.
