Measure the inside of the glass before finalizing your engraved cubes.
A glass can look roomy in a photograph and still be too narrow for a square cube. The outside diameter, advertised capacity and rim width alone do not tell you whether a piece of ice will reach its intended position.
A 2-inch cube needs room for its corners
The standard WK engraved cube measures 2 × 2 × 2 inches. The diagonal across its square face is 2 × √2, or about 2.83 inches. For upright insertion into a round glass, our planning tool adds ⅛ inch across the diameter, giving a rounded-up target of 2.96 inches internally.
That allowance is WK’s planning choice, not a universal glassware standard. Tilting can sometimes change insertion, but it does not guarantee the cube fits where it must sit. Confirm with a physical sample whenever possible.
| WK format | Ice dimensions | Round-glass width with allowance |
|---|---|---|
| Standard cube | 2 × 2 × 2 in | 2.96 in |
| Tall signature block | 2.5 high × 2 × 2 in | 2.96 in |
| Clear sphere | 2.4 in diameter | 2.53 in |
| Highball spear | 5 high × 1.25 × 1.25 in | 1.90 in |
This table compares catalog shapes; it does not mean every format or design is available engraved. Ask us to confirm custom-format feasibility.
Rocks glasses and tapered tumblers
Measure the narrowest inside opening the piece passes through, then the width at the height where it will rest. A wide rim can conceal a much narrower base. Check usable internal height too: a tall block needs headroom for the drink and garnish, and the ice may float above its resting position.
Martini and coupe glasses
A broad rim does not create a broad flat base. A conical bowl may hold a square piece high in the glass, leaving less room for the drink. A lower-profile custom piece can be worth discussing, but its square footprint still matters. Send the glass model, internal dimensions and intended drink volume before choosing a thickness.
Ask your bartender whether adding serving ice suits the cocktail. Many martinis and other up drinks are designed to be strained into a glass without serving ice.
What to send us
- A link or model number for the exact glass.
- Internal rim width and the narrower width where the ice will sit.
- Usable internal height or bowl depth.
- A side photograph and an overhead photograph with a ruler for context.
- The cocktail, pour volume and garnish plan.
Test the complete serve
Try the actual glass with the proposed ice, recipe and garnish. Check insertion, room for liquid, the visibility and orientation of the design, and whether service feels practical for the bartender. An empty-glass test alone misses liquid displacement and floating position.
