Does 「2メートルくらい」 really mean "2 meters or slightly more" instead of "approximately 2 meters"?


From [a tutorial](https://bunpro.jp/grammar_points/%E3%81%94%E3%82%8D)
contrasting ころ with くらい:

> **2メートルくらい** の所に印をつけてください。 (Correct)
>
> Please make a mark around the 2 meter point. (Natural Japanese, as an
> approximation is being discussed)
>
> **2メートルごろ** の所に印をつけてください。 (Incorrect)
>
> Please make a mark within the span of 2 meters. (Unnatural Japanese, as the
> listener would think that marking a line anywhere within the two meter space
> is fine)

For context, I have seen elsewhere that くらい can mean

  * "around" or "approximately"
  * "to the extent that"
  * "at least"

and it seems like a unified definition of all of these would be something like
"to the minimum extent of".

**My overall question:** does 「 **2メートルくらい** の所に印をつけてください」 _literally_ mean
”Please mark _on the 2 meter mark or slightly after_ " (with 2メートルくらい meaning
"to the minimum extent of 2 meters")?




The short answer is "No". I think you are overanalysing their attempted
explanation (which makes no sense). 「2メートルくらい」 simply means "approximately 2
meters", and as aguijonazo said in a comment, 「～ころ」 is wrong because it only
refers to time. They have attempted to say this by comparing the words "span"
and "extent", but this is incoherent English.
