It lies some distance to the west of the larger crater Coulomb, and to the northwest of the smaller Weber, and it was named after Hendrik Anthony Kramers, a Dutch physicist.

[1] The outer rim of Kramers is heavily eroded and worn, although the perimeter of the original crater can be readily discerned.

The younger, but comparably sized formation Kramers C intrudes into the northeast rim, and the two form a crater pair.

Kramers lies within the Coulomb-Sarton Basin, a 530 km wide impact crater of Pre-Nectarian age.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Kramers.
