A t-shirt mockup is an image that places your design on a real shirt photo so buyers can see what the printed product will look like. A convincing one bends the design into the fabric's folds, takes on the photo's light and shadow, lets the knit texture show and puts the print where a printer would really put it, at its real size.
This is for print on demand sellers whose listing photos look "photoshopped" even when the artwork is good. On Etsy the buyer cannot pick the shirt up, so the photo carries the first decision, and a flat paste-on can make a strong design look cheap. Below are the details that separate a realistic mockup from a sticker laid over a picture.
Paste-on or realistic: a quick checklist
Run any mockup past these seven points. The middle column lists what makes an image look fake, and the right column shows what a realistic mockup does instead.
| Detail | Gives away a paste-on | What a realistic mockup shows |
|---|---|---|
| Folds | The design stays flat while folds run under it | The design bends with every fold |
| Light and shadow | The print is equally bright everywhere | The print takes the photo's light and shade |
| Fabric texture | The print area is smooth and the knit stops at its edge | The knit texture shows through the print |
| Placement | Down on the belly or pressed against the collar | At chest height, a sensible distance below the collar |
| Size | Bigger than the printable area | Within the producer's print area |
| Objects in front | The design runs over a hand, hair or a strap | Objects in front stay in front |
| Colour | The shirt colour differs from the real blank | The colour matches the real blank |
We collect worked examples of these problems in mockup mistakes that make Etsy listings look fake.
Folds and light: the design has to move with the fabric
A real shirt never lies perfectly flat. Small folds form across the chest, under the arms and at the waist, and a print bends with them. On a paste-on, the folds pass under the design while its lines stay ruler-straight. In a good mockup the lettering curves gently with the fabric and the edges break slightly at each fold. In Photoshop this is usually done with a displacement map.
Light works the same way. The light in a photo comes from one direction and leaves bright and shaded areas on the fabric, and the print has to carry that light too: darker on the shaded side of a fold, a touch lighter where it faces the light. On dark shirts, white ink should not glow like a patch on black fabric. It should take the fabric's shadows as well, which we cover in mockups for dark shirts. For a quick test, shrink the image to phone-screen size and see whether the design reads as part of the fabric or as a label on top of it.
Texture and honesty: show the print the buyer will get
Look closely at a cotton tee and you can see the knit. In a realistic mockup that texture shows faintly through the print, because the print sits on the fabric surface. If the texture stops at the edge of the design and the print area looks like a smooth digital surface, the eye catches it at once.
Here realism and honesty are the same thing. The print method sets how the product looks: a DTF print, for example, is a thin, smooth layer you can feel sitting on top of the fabric. Your mockup should not promise a texture or sheen the product will not have. Etsy Purchase Protection does not cover an item that doesn't match the listing description, so any gap between the photo and the shirt in the parcel becomes your problem.
Placement and size: where a printer really prints
Placement is one of the biggest giveaways. When a design drifts down to the belly or presses against the collar, the image looks odd even if the buyer cannot say why. We explain how far below the collar a chest print should start in where to place a design on a shirt.
Size has to be real too, and print areas vary by provider. One large provider's older standard front print area was 12 x 16 inches, and it now uses 15 x 18 inches on select DTG tees, while other providers differ. Do not show the design bigger in the mockup than your producer's template allows, or the shirt that arrives will look smaller than the photo. And when a hand, hair or a bag strap crosses the design, it has to stay in front of it. A design that runs over those objects instantly looks like a collage.
Colour, background and the full photo set
The shirt colour should match the real blank. A heather grey is not a solid grey, and the faded tone of a garment-dyed shirt is not a bright dyed colour. Choose a mockup photo of the same style and colour you are going to sell.
Etsy's photo rules support a realistic photo set. A listing can hold up to 20 photos and 2 videos, and Etsy recommends photos at least 2000 pixels wide and high. Its Search Visibility page looks for a primary photo that shows one finished product rather than a collage, clear and well lit. Because Etsy does not support transparent .png files as listing photos, export the mockup with its background. For when to use which kind of shot, see flat-lay vs model mockups.
How Alomations renders realistic shirt mockups
Smart mockups in Alomations render your design onto product photos with real fabric folds, shading and light, so the folds, light and shading from the checklist above are handled for you, and they are free to use. Objects in front of the design, such as a hand or a strap, stay in front. A front mockup can carry its own chest-logo spot, a zoom (framing) control lets a product shot taken from far back fill more of the image, and flat-lay shots get a background picker. Before the run you can preview every colour and every side, and every mockup is downloadable. More in smart mockups in Alomations.
The built-in mockup library has ready product photos for the catalog products, so you can list without owning a shirt photo. On paid plans you can also upload your own photos, set the print area once and reuse it in every run, and change the shirt colour of your own photo live in Mockup Preview. Etsy allows 20 images and 2 videos per listing, and smart mockups count toward the 20.
Frequently asked questions
How many t-shirt mockups should a listing have?
Etsy allows up to 20 photos per listing, but there is no magic number. Answer the questions a buyer has: the shirt from the front, the main colours, a close-up of the print, a size chart and a flat-lay or lifestyle shot.
Why does the shirt colour in my mockup look different from the real one?
Screens show colour differently, mockup photos may be edited, and garment-dyed shirts can vary from batch to batch: the Comfort Colors spec sheet asks you to allow for slight color variation in production and washing. Use a mockup photo of the same style in the same colour.
Which mockup should be the first photo?
Etsy says the first photo should be horizontal (landscape) or square, with the subject clear in all 3 views used across Etsy. A single, centred front shot of the shirt usually does that well.
Are free mockups realistic enough?
Some are. Judge them against the checklist above, and check that the licence allows commercial use before you put one in a listing.
