Measure your normal setup
Measure your coffee machine before buying a tall latte glass. The relevant space is the gap between the surface the glass rests on and the lowest part above it. On a manual espresso machine, that may be the fitted portafilter spout rather than the machine’s body.
Set the machine up exactly as you normally use it. Include the drip tray, a cup platform if fitted, and any scales. Measure the usable height, then consider the movement needed to slide a glass in and lift it out. A glass that only just matches the gap on paper may be awkward in daily use.
Published machine specifications can help, but read their conditions. De’Longhi says its Dedica Style EC685 can accommodate glasses up to 12cm using its two-tier cup holder. That is a model-specific figure, not a rule for every espresso machine. For comparison, the ZWILLING Sorrento 350ml glass is listed at 13.9cm.
Compare exact dimensions
Check width as well as height. A handle can reach beyond the circular body, and two glasses side by side may need more room than expected. If you use a narrow tray, compare the glass’s base and overall width with that surface.
Do not remove machine parts simply because a taller glass would then fit. Use only the configurations described for your machine. If direct brewing is inconvenient, consider a shorter vessel for the espresso and pour it into your serving glass.
Keep your measurement in your phone alongside the exact machine model. When comparing listings, use product dimensions rather than parcel dimensions. If the retailer leaves height unstated, ask before buying instead of estimating it from a photograph.
Keep a useful shopping note
The best fit is a glass that leaves you room to work comfortably, not merely one that can be squeezed into the available gap.
