What is the length of the us border?

Answer 1

the length of the U.S.-Mexican border is estimated at 1,933 miles.

Answer 2

with Canada about 5525 miles

with Mexico about 1996 miles

with the United Kingdom about 40 miles

& with russia about 32 miles

so about 7593 miles in all

note added to this the second version

territorial sea limits abutting those of no other country but only the high seas are not normally considered international borders

tho in some sense these are indeed included in the border or outline of a country

&

such limits of the united states do extend for many thousands of additional miles fringing all the Coastlines of even the remotest island possessions

& thus might perhaps double or triple the above total length estimate

if their length is considered & estimated & added to it

& yet doing all that would not strictly answer the question

which is seemingly only about some actual international border of the united states

tho it is not clear with which of the other countries

if not indeed with all 4 of them

second note

an earlier & simpler answer albeit in kilometers was rightly vandalized by someone who evidently realized miles trump kilometers in the united states

& who may also have needed to see the first note

for which thanx
