Thank you for your question. It appears to be a mugo pine, described here: https://landscapeplants.oregonstate.edu/plants/pinus-mugo
We can't tell you how large it will get at maturity, because we have no information about whether it might be a dwarf variety, described in the article, or whether it is a "standard" variety. You might try taking your photo to a garden store that specializes in evergreens, and ask someone there. Good luck!
