How to measure your tumbler (60 seconds)
- Top circumference: wrap a flexible tape — or a strip of paper you mark and measure flat — snugly around the cup just below the rim.
- Bottom circumference: repeat the measurement near the base, where your wrap will end.
- Height: measure the straight distance between those two lines (not along the curve of the cup).
- Enter the three numbers above. If top and bottom are equal, your cup is straight and the template is a rectangle; if they differ, the generator builds the curved sector template your tapered cup actually needs.
Tumbler wrap size chart (starting points — always confirm by measuring)
| Tumbler | Top circ. | Bottom circ. | Height | Template type |
|---|---|---|---|---|
| 20 oz Skinny — Straight | 9.30 in | 9.30 in | 8.20 in | Rectangle 9.3 × 8.2 in |
| 20 oz Skinny — Tapered | 9.55 in | 7.05 in | 8.20 in | Curved sector |
| 20 oz Regular — Tapered | 10.05 in | 7.55 in | 7.90 in | Curved sector |
| 30 oz Skinny — Straight | 10.35 in | 10.35 in | 9.60 in | Rectangle 10.35 × 9.6 in |
| 12 oz Kids / Sippy | 8.60 in | 6.90 in | 5.90 in | Curved sector |
Why tapered wraps are curved
A tapered tumbler is a frustum — a cone with the tip cut off. Unwrapping a cone gives you a band of a ring (an annular sector): the top edge of your wrap is a long arc, the bottom edge is a shorter arc, and both share the same center point. This generator computes that geometry exactly from your three measurements, so the design meets cleanly at the seam and stays level all the way around the cup. A plain rectangle forced onto a tapered cup is the #1 cause of wrinkled sublimation wraps and designs that climb uphill at the back.
FAQ
What size is a 20 oz skinny tumbler wrap?
Straight 20 oz skinny: typically a 9.3 × 8.2 in rectangle. Tapered 20 oz skinny: a curved template from roughly 9.55 in top / 7.05 in bottom circumference at 8.2 in height. Brands vary — measure your cup before printing.
How much bleed should I use?
0.125 in (3 mm) on every edge is the standard default for sublimation. The pink line in the preview is your cut line including bleed; the blue dashed line is the true design boundary.
What does the seam overlap guide do?
It marks where the wrap's leading edge will sit under the trailing edge when you tape the transfer. Keep critical text and faces out of that strip (shown for straight wraps; on tapered templates it follows the left edge of the sector).
Is my artwork uploaded to a server?
No. Everything — the geometry, the preview and the 300 DPI exports — runs in your browser. Your files never leave your device, which is also why the tool works offline once loaded.
Can I use the templates commercially?
Yes — templates you generate here are yours to print and sell with your own artwork. The size presets are community-standard starting points; final fit is your responsibility to verify on your cup.
