Hey guys I'm new here! Just want to say I'm loving LanguageCrush so far. Coming from LingQ and I'm loving the differences here.


I have a quick question, how many words are needed in LanguageCrush to reach a decent amount of fluency, say B2? B2 In terms of reading anyway. 

I know for LingQ it's probably around 15k to 20k+ but is it the same for language crush as well?

Welcome Keeno!

That is a good question. We have not tried to put a number on that, but it should be about the same as LingQ, since we have a similar methodology.

The rule of thumb I use is that vocabulary size roughly doubles between levels. So 500 at A1, 1000 at A2, 2000 at B1, and 4000 at B2 (and 8000/16000 for the C levels). Dunno how accurate this is but it feels broadly correct to me.

I use the same rule of thumb about doubling, but I assume C2 is 20000 (since I hear that mentioned fairly often) and work downwards for the lower levels. But these numbers are supposed to be "headwords". What the OP was asking about was LC stats, which count all derivative words separately, so our stat numbers will be higher than the actual headword numbers.

old thread but i am approaching 4000 (not all of them are through this website) and I can't help but feel it will take closer to 6k-8k for B2
