What Size Should a T-Shirt Design Be? Front, Back, Chest & Sleeve Sizes

The answer to “what size should a t-shirt design be” starts with one number: its width. Choose the spot on the garment and the width is set; the height comes from your artwork. Here is the whole standard on one table, with the pixel width you need at the 300 dpi we print at.

Read the table as our standard print size for shirts, not a law of nature. Across the trade, full fronts usually land between 10″ and 12″ wide and chest logos between 3″ and 4″, and our chest logo size guide walks through that range. We print 11″ and 3.5″ because those two widths sit well on every adult size we sell, which the next section explains.

Two details change how you set up the file. The width is the width of the ink, not of your canvas: the transparent margin around your art is trimmed off before the print file is sized, so empty space in your file never makes the print smaller. And “left chest” is named from the wearer’s side, so as you face the shirt the logo sits on your right. How far below the collar and how far off centre each print sits is covered in our guide to logo placement on shirts.

Lay our everyday tee flat and measure across the chest: an adult small is about 18″ wide and a 5XL about 32″. An 11″ print covers roughly 61 per cent of the small and a third of the 5XL. That sounds like a big spread, but people read a print against the person wearing it, not against a ruler. On a small, 11″ still leaves about 3½″ of shirt on each side; on a 3XL it still reads as a full front rather than a badge.

So our standard is one adult print size across every adult size, and one youth size, for each design. That is how most shops run an order, for a mechanical reason: on a screen-printed run, every print size needs its own set of screens, one per ink colour, so a second size is a second setup. On a DTF run, a second size is only a second transfer file.

Kids are the exception, and the reason the youth standard exists. A youth XS tee is 14″ across the chest, so an 11″ print would run almost from side seam to side seam. At 8″ it covers 57 per cent of the XS, close to the share 11″ takes of an adult small. When an order mixes adult and youth sizes, the same artwork comes out as two print files: 11″ for the adults and 8″ for the kids.

When to ask for a separate small-size file: when most of the order is XS and S and the design is large and square, so 11″ × 11″ would swamp the smallest shirts, or when you want the print to look proportionally the same on an S and a 4XL standing side by side. Say so in the notes at checkout or on the free quote form before you order. On a large screen-printed run, expect the second size to add a setup; on a small DTF order it is only a second file.

The width is fixed; the height is whatever your artwork’s proportions make it. A square logo at 11″ wide is 11″ tall, and a wide wordmark at 11″ might be 3″ tall. The limit is physical: every garment has a point where a taller print would run into a seam, a pocket or the end of the flat print area. When a design would be taller than that at 11″ wide, we cap the height and let the width come down in proportion.

The tall-crest column is the one to read. A crest 1.8 times taller than it is wide would be 19.8″ tall at 11″ wide, longer than any shirt front can take, so it prints 7.6″ × 13.6″ on a tee and 5″ × 9″ on a hoodie. Wide art always gets the full 11″. Square art gets it everywhere except the hoodie front.

The quick check before you design: divide your art’s height by its width and multiply by 11. If the answer is bigger than the limit for your garment, the print will come out narrower than 11″. On a tee front that starts once a design is about a quarter taller than it is wide. If the full width matters, rework the layout rather than squeezing it: set the name beside the crest instead of under it, or move the tall version to the back, where every garment has more height.

The hoodie front is the print that catches people out. The pouch pocket sits where a tall tee print would end, so a hoodie front print can be at most 9″ tall, and it starts 3.5″ below the hood opening rather than 3″ below a collar. Any design taller than about 82 per cent of its width cannot be 11″ wide there; even a square logo prints 9″ × 9″. The back has no pocket and takes up to 15.6″ of height.

This matters most when one design goes on tees and hoodies in the same order. A wide wordmark comes out identical on both. A square or tall design comes out as two files, the tee size and a smaller one for the hoodie, and the hoodie version will look smaller beside the tee in a group photo. If that bothers you, put the big print on the hoodie back and a chest logo on the front. You can watch the limit happen: put a square logo on a hoodie in the design studio and the front size stops at 9″. Our hoodie print placement guide covers the pocket, the seams and the drawcords in detail.

A crewneck has no pocket and a flat front, but its print area is shorter than a tee’s: 11.4″ on the front and 12.9″ on the back. A square 11″ logo fits; anything taller than square starts to narrow. A polo takes the same 3.5″ chest standard as everything else, and a chest logo is the usual polo print, because the placket and buttons run down the middle of the front.

Our print files are made at 300 dpi, which turns every width into a pixel count: multiply the inches by 300. An 11″ full front is 3,300 pixels wide, and a design as tall as a tee front allows, 13.6″, is 4,080 pixels tall. The right-hand column below is the floor where our studio starts warning you.

The studio measures every upload against the size you place it at. Under 150 dpi it suggests a sharper file; under 100 dpi it tells you plainly that the print will be blurry. Between 150 and 300, most artwork prints well, and fine lines and small text are where the difference shows.

• The dpi number in a file is only a label. What counts is the pixel count. A file 3,300 pixels across is 300 dpi at 11″ whether its settings say 72 or 300, and retyping the dpi of a 1,000-pixel file does not add a single pixel.
• Upscaling does not add detail. Stretching a 1,000-pixel logo to 3,300 pixels makes up the missing pixels, which gives you soft edges, not sharp ones.
• Bigger than you need is fine. Some print-on-demand templates ask for 4,500 × 5,400 pixels, a 15″ × 18″ canvas at 300 dpi. A file that size is more than enough for an 11″ print; it is trimmed to the ink and scaled down.

Our guide to preparing print-ready artwork covers resolution for paper and signs as well, where the rules are different.

Set the design dimensions to the print, not the shirt: the print width and the height of your art, at full size, on a transparent background. For a full front on a tee that is 11″ wide and up to 13.6″ tall, or 3,300 by up to 4,080 pixels. Leave the shirt out of the file; the studio and your free mockup put the design on the garment.

• Canva. Choose Create a design, then Custom size, and enter the size in pixels, for example 3300 × 3300 px for a square full front. Pixels are the safe unit, because the file you download is exactly that size. Download a PNG with “Transparent background” ticked (a Canva Pro option); without it, your art arrives on a white rectangle that has to be removed before it can print on a coloured shirt.
• Photoshop. File → New, 11 × 13.6 inches at 300 pixels/inch, background contents Transparent, colour mode RGB. Start at full size rather than enlarging a small document later, then export a PNG with transparency on.
• Illustrator. Set the artboard 11″ wide and keep the artwork vector. Convert type to outlines (Type → Create Outlines), embed any photos at 300 ppi at their placed size, and set Effect → Document Raster Effects Settings to 300 ppi if you use shadows or glows. Send the AI, EPS, SVG or PDF; a 300 ppi PNG export works too.

On colour: a PNG cannot be CMYK, and RGB files are normal for shirts, so there is no need to convert anything first. If a colour has to match exactly, send its Pantone reference with the file.

A vector file (AI, EPS, SVG, or a PDF exported from a vector program) stores shapes instead of pixels, so it prints as sharply at 11″ as at 3.5″ and has no pixel size to worry about. Logos, lettering and flat illustrations belong in vector. A raster file (PNG, JPG) is a fixed grid of pixels. Photographs, painted art and anything with texture are raster by nature, and need the pixel counts above.

The usual problem file is a logo saved from a website or a phone screenshot. A 600-pixel logo is about 171 dpi as a 3.5″ chest logo, which prints fine, and about 55 dpi as an 11″ full front, which prints blurry. There are three ways out: find the original file (whoever designed the logo has it), run a simple flat logo through our free in-browser vectorizer, or have it redrawn by hand through our vectorization service. Our guides to transparent PNG vs vector and preparing logo files for printing go deeper.

Plenty of orders use one design twice: big on the back and small on the chest. The chest version is the full front at 32 per cent (3.5 ÷ 11), and everything in it shrinks by the same amount. A line 1 mm thick on the full front is about 0.3 mm on the chest. A tagline 0.5″ tall becomes 0.16″, about 4 mm. Detail that reads from across a room at 11″ turns to a smudge at 3.5″. The youth version is a gentler 73 per cent (8 ÷ 11), which most designs survive untouched.

As a working rule, treat half a millimetre of line at the printed size as the floor. Thinner than that, a screen may not hold the line open, and a DTF print has too little adhesive under the line to grip through the wash. For a chest logo that usually means a simplified version: thicker strokes, the tagline dropped, the icon or the wordmark alone. Embroidery is stricter again, and text under about a quarter inch tall will not stitch cleanly.

Tall logos hit a chest limit too. At 3.5″ wide, a crest 1.8 times taller than it is wide would stand 6.3″ tall, and our chest standard stops at 4.5″, so it prints 2.5″ × 4.5″. A logo taller than 4.5″ is not a chest logo any more; it is a small full front.

Every order is reviewed by a human designer before it goes to press. A person checks artwork resolution, colour, sizing and placement, and either fixes the file or tells the customer what is wrong — it is not an automated preflight. On sizing, these are the things a designer looks for:

• Low resolution. A file that lands under 150 dpi at its print size, usually a web logo or a screenshot stretched to a full front.
• Lines and text too fine for the size. Hairlines and small taglines that hold at 11″ and vanish at 3.5″.
• A background that should not print. A white or coloured box around art that was meant to be transparent, or a faint fringe left by a background removal.
• Art too tall for the garment. A tall crest that has to narrow on a hoodie front, caught before it surprises you.
• A logo on the wrong side. “Left chest” means the wearer’s left, which is on your right as you face the shirt.
• Colours that disappear. Navy art on a navy shirt, or a thin dark outline on black.

Every order gets a free digital mockup on the actual product before any payment. Nothing prints until the customer approves it.

Customers can design their own product free at yayaprints.ca/mockup-creator — upload a logo, place it on a real garment, add print-quality text, choose colours and sizes, and order online without emailing or phoning anyone. When you upload, the studio asks where the design should go and shows the size it will print at in each spot on the front, and the resolution warning appears on the canvas while you can still swap the file. Need something other than our standard size? Say so in the notes at checkout.

How it is printed depends on the order. No minimum on DTF and DTG — we will print a single shirt. Screen printing starts around 6 pieces and becomes the best value past roughly 24–50 pieces, and orders in the hundreds are usually screen printed and quoted directly — through the free quote form, by email or by phone. A large order gets the same free mockup and human designer check as a single shirt, and on a run that big it is worth agreeing on the print size at quote time.
