Is a 157 cm. snowboard long enough for me. and 6 foot tall guy who weighs 160?

im new to snowboarding and i know that your board should be up to your chin. im 6 foot tall and after doing the math and measuring i know my board length should be about 160cm, how ever i found a good deal online, but the longest they have is 157. is that long enough? or should i give it up and look for a longer board? thanks!!!
