Its probably not a coincidence that the numbers must be 3.5" with one inch border white space, which comes to 5.5" which when doubled comes to 11" and fits nicely on a 1/2 page of standard (US) letter paper.

Note that if you have four pit placards from prior regionals stashed away, these can be used, look great and satisfy the bumper number rules-- they come with FRC logos and big black numbers on white background on a sturdy card.

I'm guessing the rules are written such that when any team that arrives with 'questionable' numbers/colors (or missing ones), the LRI can use his printer (or the FMS setup's printer) to print bumper numbers for the team, and the team/mentor can't complain that the LRI is being unreasonable in asking them to do too much 'work' to fix the problem. Inspector provides the printed numbers (maybe even on card stock) and all you need to do is find some tape and three or four places to tape them to on your bot.

I'm sure most inspectors/LRIs would rather deal with more consequential issues with teams than bumpers, bumper colors/covers, bumper zones, bumper number quality, frame perimeters, and such. Seems like the rules have largely accomplished that this year. I for one am happy about that.
