To commemorate redistricting, I decided to crank out my calculator and see what each state and territory's House delegation size would be if the Wyoming Rule or the ratio being used for the New Hampshire House of Representatives (which I'll heretofore refer to as the NH Rule) were used for reapportionment. I used 2010 Census figures for all 50 states, DC, and Puerto Rico, while I used 2011 CIA estimates for the four other outlying territories.
Seeing as how the WY and NH rules might result in a House of Representatives with a membership larger than the 435 limit it has now, I did not even bother working with a fixed limit. It's just apportionment by strict division, and I rounded up to the nearest whole number whenever applicable.
WY Rule: State Population ÷ 563,626 (WY's population per the 2010 Census)
NH Rule: State Population ÷ 3,300 (the average # of people that each NH state rep represents)
Suffice it to say, we're going to need a bigger Capitol.

THE DISTRICT of COLUMBIA
DC, being more populous than Wyoming, actually gets more representatives under the NH Rule - although all 182 of them would presumably be non-voting.
DC: 1 / 1 / 1 (182)
THE OUTLYING TERRITORIES
Under the Wyoming Rule, all of the outlying territories with the exception of Puerto Rico would be allocated just one non-voting representative, although their low populations mathematically precludes them from being allocated one at all. If the NH Rule is used, the low threshold set forth by the NH Rule allows all the outlying territories to have more than one non-voting delegate or commissioner.
Puerto Rico is the grand exception. Unlike the other outlying territories, PR is relatively large - with a population comparable to OK. PR would get 5 representatives under the current plan, 6 under the WY Plan, and 1,129 using the NH Plan if it was a state. However, given its non-voting, non-state status, it would probably just get one non-voting resident commissioner regardless of its population, like the other outlying territories and DC.
AS: 1 / 1 / 1 (20)
GU: 1 / 1 / 1 (55)
MP: 1 / 1 / 1 (13)
PR: 1 (5) / 1 (6) / 1 (1,129)
VI: 1 / 1 / 1 (33)
TOTALS
Currently, the US House of Representatives has 441 members - 435 voting and 6 non voting. In the absence of a fixed limit and if the WY or NH Rules were in place, the House might look like this:
WYOMING RULE
Voting: 547
Non Voting: 6 (11 if PR is proportionally allocated more than 1 delegate)
TOTAL: 553 (558)
NEW HAMPSHIRE RULE
Voting: 93,352
Non Voting: 6 (1,432 if all territories and DC are proportionally allocated delegates)
TOTAL: 93,358 (94,784)
I may also toy around with the idea of a "Northern Marianas Rule" given that it's the smallest overall political unit in the USA, with an estimated 2011 population of just 46,050.
