How to Design a T Shirt: The Production-Minded Approach
The most reliable way to approach how to design a t shirt is to design for the factory and the printer as well as for the customer. A tee has four things that decide the result: the blank garment, the fabric, the artwork and the method used to put it on the shirt. If you settle these in the wrong order, you often have to redo the artwork, so the workflow matters as much as the drawing.
Many first-time brands start with the graphic and choose the shirt afterwards. That works for a one-off, but for a production run it is safer to fix the garment and decoration method first, because the print method decides what artwork is possible. A design with six colours and a photograph suits a different process from a one-colour logo.
The sections below follow the order in which decisions are best made. If you want the technical document that records them, our tech pack guide explains what it should contain.
Step 1: Choose the Fit and the Blank Garment
Before drawing anything, decide what shape of t-shirt you are designing for. Fit affects where the print sits, how large it can be and how the shirt hangs. A regular tee, a boxy tee and a slim tee all have different proportions, so the same graphic can look balanced on one and awkward on another.
Common t-shirt fits and what they mean for design
| Fit | Shape | Design consideration |
|---|---|---|
| Regular or classic | Straight body, standard sleeve | Most flexible for print placement and sizing |
| Slim or fitted | Closer through body and sleeve | Smaller prints; check stretch across the chest |
| Boxy or relaxed | Wider body, often shorter length | Larger prints work; see our boxy and oversized t-shirt guide |
| Oversized or dropped shoulder | Extra width, lowered shoulder seam | Print positions move lower and outward; test on sample |
| Cropped | Shortened body length | Front graphics sit higher; check hem position |
General descriptions. Exact proportions come from your measurement chart and pattern.
Use a reference tee you already own and like as the starting point. Measuring it gives the factory a real target for width, length and sleeve, and it avoids vague descriptions such as relaxed. A neckline, collar width and rib height are worth measuring too, since they are the details customers notice first and the hardest to correct after sampling.
Step 2: Pick the Fabric and Weight
Fabric decides how the shirt feels, how it takes a print and how it behaves after washing. For most brands the choice is between lightweight, mid-weight and heavyweight cotton jersey, with cotton-polyester blends as an alternative when shape retention or cost matters. Weight is described in GSM, grams per square metre, and typical ranges depend on the style.

Grams per square metre
Typical ranges that vary by product, factory and market. Always confirm with a fabric swatch and a sample.
Heavier fabric usually hangs better and supports larger prints, while lighter fabric feels cooler and drapes. Colour matters as well: a light ink on a dark shirt usually needs an opaque base layer, while a dark ink on a light shirt is simpler, so the garment colour should be chosen before the palette is final. Our fabric GSM guide explains how weight, yarn and finish interact, and what to ask for on a swatch.
Step 3: How to Design a T Shirt Artwork File That Prints Well
Artwork preparation is where many t-shirt projects go wrong. A file that looks fine on a phone can be too low resolution or too complex to print. When you work out how to design a t shirt graphic, the first technical choice is between vector and raster files, because that decides how sharply the design can be reproduced at any size.
Vector vs raster artwork
| Feature | Vector | Raster |
|---|---|---|
| What it is | Shapes and paths defined by maths | A grid of pixels |
| Scaling | Can be enlarged without losing sharpness | Becomes blurry or pixelated if enlarged beyond its resolution |
| Best for | Logos, text, flat illustration, screen print | Photographs, textures, painted artwork, digital print |
| Typical file types | SVG, outlined PDF, AI, EPS | PNG, TIFF, PSD, high-resolution JPG |
| What to check | Text converted to outlines; clean paths; named colours | Resolution at the printed size; transparent background where needed |
Software for both types is widely available; the printer’s file requirements matter more than any specific program.
For raster artwork, a commonly used target is 300 pixels per inch at the final printed size, so a design printed 300 mm wide needs far more pixels than a social media image. Keep text as outlines, avoid mixing many fonts, and name every ink colour so the printer can match it. Pantone references help when a specific brand colour must match, and a physical colour swatch is better still.
Step 4: Choose a Print Method Early
Your artwork and your print method influence each other, so decide the method before polishing the file. A solid-colour logo is ideal for screen printing, while a photographic image points to digital printing. Our guides to screen printing t shirts and DTG printing explain each method in depth.
Print method and what its artwork needs
| Method | Artwork needs | Colour limits | Good for |
|---|---|---|---|
| Screen printing | Vector, separated into solid spot colours | Cost rises with each added colour | Repeat runs of logos and graphics |
| DTG (direct to garment) | High-resolution raster at final size | Full colour, photographic detail | Small runs and detailed artwork |
| Heat transfer vinyl | Vector shapes, cut-friendly | Flat colours only | Names, numbers, simple marks |
| DTF (direct to film) | High-resolution raster or vector | Full colour | Mixed fabrics and small runs |
| Embroidery | Simplified vector, digitised to stitches | Limited by thread colours; little fine detail | Small logos, premium finish |
General guide. The printer or factory confirms feasibility for your exact design and fabric.
Anyone learning how to design a t shirt for a real run should expect this trade-off between design freedom and unit cost. Ask for quotes on two methods when a design could suit either. The comparison will show whether your quantity favours setup-heavy or digital methods, and it can save a redesign later.
Step 5: Set Placement and Print Size on the Shirt
Placement is part of how to design a t shirt that looks good on real bodies, not just on a flat mockup. The same print placed 50 mm too high can sit on the collarbone, and the same width can look small on a boxy fit and large on a slim one. Define each placement in millimetres from a fixed point such as the centre front and the neckline seam.
Typical print positions and size ranges
| Placement | Typical print width | Notes |
|---|---|---|
| Left chest | 80–100 mm | Small logo, sits on the wearer’s left |
| Centre chest | 200–300 mm | Standard graphic position below the neckline |
| Full front | 280–350 mm | Large print; check on the smallest and largest sizes |
| Full back | 280–350 mm | Large graphic below the collar |
| Upper back or back neck | 70–100 mm | Small brand mark under the collar |
| Sleeve | 60–90 mm | Small badge or text clear of the seam |
Typical starting ranges for adult sizes. They vary by brand, fit and print method and must be confirmed on a sample.
Plan how the design changes across the size range. Many brands use one print size for small to large and a larger one for extra-large and above. Record this as a size grading rule in the tech pack so the sample and bulk follow the same logic.
Step 6: From Mockup to Tech Pack and Sample
A mockup is an image of the design on a shirt. It is useful for deciding layout and for showing the idea to others, but it is not a sample. It cannot show how ink sits on fabric, how a collar rolls or how a print moves when the shirt is worn. Treat it as a starting point and then move to a physical sample as quickly as possible.
The tech pack turns the design into instructions. It includes the flat drawing, measurements, fabric and GSM, colour references, print positions and sizes, labels, stitch details and packing. Our guide to working with a t-shirt manufacturer shows how this fits into the wider process, and packaging details are covered in the clothing packaging guide.
From idea to approved bulk
- ConceptSketch the idea and fit; choose a reference tee
- Fabric and blankSelect composition and GSM; get swatches
- ArtworkPrepare vector or raster files for the chosen method
- Tech packRecord measurements, placements, colours and trims
- SampleMake a physical sample on the real fabric and review it
- Revise and approveAdjust fit, print or colour; approve a final sample
- BulkProduce and inspect against the approved sample
A general workflow; timings depend on the product, print method and factory.
Review the first sample on a person, not only on a table. Check fit, print position on the body, wash performance and handfeel, then write down every change request so the revised sample can be compared with it.
Pre-Send Checklist and Common Mistakes
Before you send a design to a factory or printer, run through a short checklist. It catches the mistakes that cause most delays and reprints.
Checklist before sending artwork
- Fit and reference garment chosen, with measurements
- Fabric composition and GSM stated
- Artwork supplied as vector or high-resolution raster at final size
- Text converted to outlines and ink colours named
- Print method chosen and the artwork suited to it
- Placement and print size in millimetres for each position
- Size rule for the print across the size range
- Labels, neck print or neck label defined
- Wash test and sample approval planned before bulk
Add care labels, size labels and packing requirements as your tech pack requires.
The mistakes that most often cost brands time are designing the graphic before the shirt is chosen, approving colours from a screen, using low-resolution images, and assuming that a mockup shows how the real garment will look. A wash test on a sample will also show whether the print and fabric work together after laundering. Keep one approved sample, signed and dated, as the physical reference that bulk is checked against.
It also helps to review the whole design as a set rather than shirt by shirt. If you plan several colours or several graphics, check that the print positions, sizes and neck labels are consistent across them, because a range that looks coherent on a rail is easier to sell and easier for the factory to produce. Write down the decisions you made and why, so the next season starts from a record instead of from memory.
