The dinar is written to three decimals, so a Kuwaiti total eats three digits before the dinars even start — which is how a short display ends up rounding an invoice column. Twelve digits leaves room: a long total in dinars and fils stays readable instead of turning into notation. The rest of the case is the keypad. A fixed desktop pad sits under your fingers, doesn't move when you look away at the paper, and doesn't hide the running total behind your thumb the way a phone does.

Questions people ask
Why do 12 digits matter here?
Because the dinar carries three decimals. Three of your digits are spent on fils before you've counted a single dinar, so a shorter display runs out on totals that aren't even large.
Isn't the phone calculator enough?
For one sum, yes. For forty lines off a paper invoice you want keys you don't have to look at and a screen your hand isn't covering — that's why desk calculators outlived the smartphone.
