How the template is worked out
A straight tumbler unrolls into a rectangle. Its width is the distance around the tumbler, its height is the area you print on.
A tapered tumbler is a slice of a cone, so it unrolls into a curved strip. The wide end becomes the long outer curve and the narrow end the short inner one. A rectangle on a tapered tumbler leaves a gap at the narrow end or wrinkles at the wide end.
A little extra width at the seam, about 0.1 in, keeps a white line from showing where the ends meet.
The downloads are made in your browser. The PNG is saved at 300 DPI, so it opens at the right size in Canva, Photoshop and Design Space. The SVG is an outline you can cut or use as a guide.

Approximate sizes with 0.1 in extra at the seam. Brands differ by a few millimeters, so measure your tumbler in the calculator for a wrap that fits exactly.
What the calculator gives you
For a straight tumbler you get two numbers: wrap width and wrap height, in inches and in pixels at 300 DPI. For a tapered tumbler you also get a curved outline, because a tapered wall unrolls into an arc. A plain rectangle printed for a tapered cup leaves a white wedge at the seam and wrinkles at the bottom.
The template download is a transparent PNG at the exact print size, with a dashed line marking the seam overlap and a second line marking the edges of the printable band. Drop it into Canva, Photoshop, Procreate or Cricut Design Space as the bottom layer, put your design on top, then hide the template before you export.
How the wrap size is calculated
The width of a straight wrap is the tumbler’s circumference: diameter times pi (3.1416). The height is the printable band, the straight section between the lip at the top and the rounded base ring at the bottom. It’s always shorter than the tumbler itself.
A small overlap goes on top of the circumference. Without it, any rounding in the diameter or any slack in the shrink wrap leaves a thin uncolored line at the seam. The calculator adds 0.2 inches by default and lets you change it.
MakerFlo’s 20 oz skinny shows how this works out in practice. The blank is straight, 2.90 inches across and 8.63 inches tall, and MakerFlo gives its sublimation template as 9.325 x 8.125 inches.
The circumference is 2.90 x 3.1416 = 9.11 inches, so the published width carries about 0.2 inches of overlap. The height is half an inch shorter than the tumbler, because the lip and the base ring don’t take a print.
Skinny tumblers from different factories differ by a few hundredths of an inch, which is enough to show a gap. Measure your own blank with calipers or a flexible tape before you trust any generic 20 oz template, including the preset in this calculator.
Straight or tapered: how to tell
Stand the tumbler on a table and lay a ruler flat against its side. If the ruler touches the wall from top to bottom, the tumbler is straight. If a gap opens up toward the base, it’s tapered. You can also measure the diameter at the top and the bottom of the printable band. A difference of more than about a tenth of an inch is enough to need the tapered outline.
Most sublimation skinnies on the market now are straight, because a straight wall is easier to wrap. Tapered skinnies, older stainless tumblers and the big 40 oz cups with handles still need the curved template.
Worked example: a tapered 20 oz skinny
Your blank measures 3.0 inches across at the top of the printable band and 2.6 inches at the bottom, with a 7.5 inch tall band in between. Pick Tapered and enter those three numbers.
The top edge of the wrap has to cover 3.0 x 3.1416 = 9.42 inches, and the bottom edge only 2.6 x 3.1416 = 8.17 inches. The difference of 1.25 inches is why a rectangle fails. Cut the rectangle to the top and the bottom bunches up. Cut it to the bottom and the top seam gapes.
The calculator draws the wrap as a slice of a ring. The outer edge has a radius of 56.27 inches, the inner edge 48.77 inches, and the slice spans 9.6 degrees. You don’t need to draw any of that by hand, but those numbers explain why the curve looks so gentle on screen: it’s a small piece of a very large circle.
The finished outline fits in a box 9.41 x 7.67 inches, or 2824 x 2302 pixels at 300 DPI, before the overlap. Design inside the curved outline, keep text at least a quarter inch away from the curved edges, and print at 100 percent scale. A “fit to page” setting in the print dialog shrinks the wrap, and a shrunk wrap no longer reaches all the way around the cup.
A 9.41 x 7.67 inch wrap fits on Letter paper turned sideways (11 x 8.5 inches), with room to spare. Check every result against the paper your sublimation printer takes. Taller tumblers can outgrow Letter, and the calculator flags any wrap that needs 11 x 17 paper.
Designing so the seam disappears
The seam is where the two short edges of the wrap meet. Any design element that crosses it has to line up perfectly from both sides, which is hard to do on a curved surface. A few habits help.
Keep text and faces away from the seam. Put the main design opposite the seam, and turn the seam to the side a hand covers when someone holds the cup.
Use a background that repeats. A repeating pattern, a solid color or a gradient that runs top to bottom hides small misalignments. A gradient that runs left to right shows them.
Extend the background past the template edge. Fill the overlap area with the same background so the seam lands on color instead of white.
Before you press
Mirror the print before it goes to the printer, or every word on the cup comes out backwards. Some design apps and printer drivers mirror for you, so turn it on in one place only. Trim the printed wrap along the outline, wrap it snugly, and tape both short edges and the top and bottom with heat resistant tape so nothing shifts.
A shrink wrap sleeve or a tumbler press holds the paper tight against the steel. Time and temperature come from the blank’s maker. Even MakerFlo’s page gives slightly different press settings in two places, so run a test cup before a full batch.
If you own a Cricut Mug Press, check that your blank fits before you design for it. Cricut lists compatible non-Cricut mugs as 3.2 to 3.4 inches in diameter and up to 4.72 inches tall, with a straight pressing area.
A 20 oz skinny falls outside those numbers, so it goes in a convection oven or a tumbler press.

Frequently asked questions
What size is a 20 oz skinny tumbler template?
For a straight 20 oz skinny, usually about 9.3 x 8.1 inches. MakerFlo’s own blank, for example, uses 9.325 x 8.125 inches. Blanks from other makers differ slightly, so measure the diameter of yours and run it through the calculator.
How do I work out the wrap width for any tumbler?
Multiply the diameter by 3.1416 to get the circumference, then add about 0.2 inches for overlap. A 2.9 inch tumbler needs a wrap 9.11 inches around, or about 9.3 inches with the overlap.
Why does my sublimation wrap leave a gap at the seam?
Usually one of three things: the template was made for a slightly thinner blank, the print was scaled down by a “fit to page” setting, or the wrap had no overlap. Measure the blank, print at 100 percent, and add 0.2 inches to the width.
Do I need a tapered template for a skinny tumbler?
Only if the tumbler is tapered. Lay a ruler against the side. If a gap opens toward the base, use the tapered setting. A rectangle on a tapered cup wrinkles at the bottom and gapes at the top seam.
What DPI should a tumbler sublimation template be?
300 DPI. People look at a tumbler from a foot away, and at lower resolutions text and fine lines print with soft, fuzzy edges. The PNG download is set to 300 DPI at the exact print size.
Can I use the template in Cricut Design Space or Canva?
Yes. The PNG imports into Cricut Design Space, Silhouette Studio, Canva and most image editors. Keep it as the bottom layer, design on top, and hide it before you export or print.
