The dimensions mentioned are approximate
and is only meant for estimation purposes.
3.35 Inches
Note: After printing this on an A4 sheet, cut along the outer edges of one or more of the 3 charts
above (as many as required), and fold each of them backwards in half along the dotted lines
running through the middle of each of the charts. Once you do that, it would look like a business
card, where both sides are printed when you flip the chart over. It is recommended to laminate all
the 3 charts above, just incase you lose one or two, and keep one card in your wallet. Enjoy, and
happy subnetting! Suggestions and Feedbacks are most welcome on my youtube channel or video.
