How much does the average Christmas card weigh?

[koster]

I'm sending one to the US, so need to know if it's under 10g, under 20g, under 40g, or under 100g, but I don't think the kitchen or bathroom scales are particularly accurate for this kind of thing!

Unless you have a special scale for small weights the only way is to take it to the post office scale.

20g. average size, 30g. larger ones.

Put say thirty or more on the kitchen scales, then divide the result - should be close enough (providing it's not marginal!)

...I weighed some (to nearest gram)!

Thanks everyone!
