 OFFSET 0,2 COMMENTS The title is copied verbally from the second example "SUB[44]" of the linked xkcd webcomic number 2016 (subtitled "OEIS keeps rejecting my submissions"). To make the definition exact, the full title should be: The nonnegative integers sorted by increasing width of bounding box when printing their decimal representation using the Helvetica font, and in case of ties, sorted by increasing value. The differences to the corresponding sequence A316599, which uses the Arial font, are the different width data for the digit characters and the absence of kerning for the number pair "11" in Helvetica. So the print width becomes a function of the number of printed digits, of the left margin of the bounding box of the most significant digit and of the right margin of the bounding box of the least significant digit. See the comment in A316599 for more information.
