Put a soft tape around your dominant hand at the widest part of the palm, just below the knuckles, with the thumb held out of the way and the hand relaxed. Close the tape until it touches without pressing. Read the number in inches. That figure is hand circumference, and it is what most Fioretto glove listings size by.
Use the dominant hand. It is usually a tenth to two tenths of an inch larger than the other, and a glove that fits the larger hand will fit the smaller one. The reverse does not hold.
We pulled the sizing table off every glove listing in this catalog. 10 distinct tables came back off 32 pages. 7 of them measure circumference, 3 measure hand width, and even inside the circumference group the bands move: one model starts small at 7 inches, another starts small at 8.3. That gap of 1.3 inches is wider than three whole bands on the tightest of these charts, and every one of those models calls the result S.
The practical consequence: a size letter that fitted one Fioretto pair is not a promise about the next one. Read the chart on the page you are buying from. Every product page in this catalog reproduces the table from its own listing, and the calculator on that page runs off that table rather than a generic one.
A width chart measures straight across the flat palm, one edge to the other. A circumference chart goes all the way around. The two numbers differ by roughly an inch and a half on the same hand, so applying a width measurement to a circumference chart puts you two sizes too small. The chart heading on each product page states which one it uses.
Circumference sets the glove size, but two hands with the same palm measurement can have very different fingers. If your fingers are long for your palm, the fingertips of a correctly sized glove will feel tight before the palm does. There is no chart for this in the range, so read the listing reviews on that specific model, where long-finger complaints show up consistently when they exist.
Calculator
Merged from the 7 distinct circumference charts in this catalog. It tells you the band you fall in and how close you are to its edge, which is the part a plain chart will not do for you.
Product pages carry their own chart and their own calculator. Where the two disagree, the product page wins.
Bands merged across 7 charts, overlaps split at the midpoint.
