In the US, most double-hung windows installed in the last few decades
are factory-built. Most installers do not make to measure, but order
factory-made windows to match the size. In my area, there are about
seven or eight popular sizes in stock, and be able to special-order
prefabricated windows to fit other sizes. Bespoke joinery for windows
is nearly a thing of the past around here - windows are ordered from a
company like Andersen or Pella.
There's a much faster lead time if a builder confines himself to a
reasonably small set of sizes. For instance, one dealer near me can
supply double hung windows for immediate delivery, but only in
standard widths of 24, 28, 32, and 36 inches for the rough opening,
and standard heights 38, 46, 48, 54 and 62 inches. (It's not all
combinations, either, for instance the ones with a 48-inch height are
stocked only in 32 and 36 inch widths.)
