On the Grammarly website, they have the following sentence:

You can upload a document which size is under 4 MB

As a fan of irony and grammar, I'm curious as to whether the bolded portion is grammatically correct. It sounds really awkward, and I've honestly never seen anyone use that phrasing. I would've opted for one of the following:

You can upload a document whose size is under 4 MB

You can upload a document which has a size of less than 4 MB

You can upload a document with a size under 4 MB

You can upload a document smaller than 4 MB

Is their version acceptable?

    Your instinct is correct. Their version is not. Feb 1, 2017 at 22:47

    Just wondering - what do you get when you feed the paragraph back to grammarly's grammar checker?

  • I agree that this form is odd, but some even highly educated native speakers seem to use it. Here is one such example form David Foster Wallace: "This reviewer's family is roughly 70 percent SNOOT, which term itself derives from an acronym, with the big historical family joke being that whether S.N.O.O.T. stood for "Sprachgefühl Necessitates Our Ongoing Tendance" or "Syntax Nudniks of Our Time" depended on whether or not you were one" (Footnote 3 at harpers.org/wp-content/uploads/…). Seems odd for a SNOOT like DFW. Or was he being ironic? Feb 2, 2017 at 1:15

    @Lawrence Lol, I've got to try that now. Update: didn't flag it Feb 2, 2017 at 2:05
  • which has a size would be better with that instead of which.

As Janus Bahs Jacquet observes in a comment beneath the poster's question,

Your instinct is correct. Their version is not.

Tacitly (and belatedly), Grammarly seems to have recognized the ungrammarliness of its originally posted wording. The wording that now appears on the cited support page is

You can upload a document of 4 MB or less.


You are correct. Even though "you" is the subject of the sentence, and "can upload" is the predicate, which size indicates a question, and since there is none, rather, there is a statement, the sentence is grammaticaly incorrect. However, the english reader should be able to figure out what they mean, so it gets the point across and works, but is technically incorrect and should be avoided.

    which doesn't indicate a question, it's a relative pronoun. It's just the case that it's the wrong pronoun for this use.
