At the moment, you can mention fabric size in cm or inches. Is it important to have yards as an option?

For meters, I think it's less of a problem, but with yards mathematics is a bit more complex...

I'm an Aussie girls so cm's for me

Yes, I think that being able to list fabric in numbers of yards and fractions of yards (1/8, 1/4, 3/8, 1/2, 5/8, 3/4, 7/8) is pretty important if it is feasible. This is what is used on the pattern envelopes.

Yes, I will talk to the guys :)

Do I understand correctly that it's only about length, not width? I am used to cm, so I am not very sure how it works :)

And then we need to add it to the stash as well I guess...

Yes, only the length of fabric is referred to in yards in the US. The width would be referred to in inches, if it is referred to.
I'll put a link to the fabric requirements for Colette's Laurel pattern, just as an example of how the yardage charts on patterns usually look. The fabric widths that are common to the type of fabric required for the pattern are listed on the left, in this case 45 and 60 inches. Next to each is the yardage needed for each size of the pattern.

Please forgive me if I'm telling you things you already know :)

Thanks for the info! ))

I've seen yards in length of the pattern requirements, but then I was unsure if it's the same with width and canceled that calculation at first.

But yes, we'll definitely add it!

Thanks!

Yeah -- I learned this the hard way, some USA fabric retailers just don't really understand metric and want you to order by yard amount, only. So at one yard being 91.44 cm... the conversion math gets nasty fast.

It should be both meters and yards for length of fabric and both cm and inches for width of fabric, IMO.

Okay, I'll ask the guys, but I have a feeling that it is easier to have everything for everything :) I'll get back to you on this )))

Good point! I didn't mean to sound all "US-centric" by leaving m and cm out. I figured metric went without saying, but I'm glad you said something.

It's not hard to convert yards and meters at all. If you think in yards, a meter is about 1-1/8. If you think in meters, a yard is about .9.  So if you need 3 meters of fabric, you need 3-3/8 yards. If you need 6 meters, you need 6-3/4 (think of it as 6-6/8). For every eight meters you need, you'd need 9 yards (8-8/8). I realize it's hard for meter-thinkers to start thinking in inches, feet, twelves, eighths, quarters, and thirds, but for us imperial thinkers, base ten should be a snap...we've already mastered some very convoluted, medieval measurements! :)
