What it means
くらいのものだ expresses that something is virtually the only person, thing, or possible action that fits a situation. It highlights a sharply limited range and often corresponds to “the only ...,” “about the only ...,” or “all one can do is ...” in English. It commonly follows a noun or a verb in the dictionary form and is used when the speaker views the stated option as the sole realistic possibility.
Usage note
くらいのものだ is more restrictive and emphatic than a simple statement with だけ. With nouns, it usually means “about the only ...,” so it can allow a small degree of approximation rather than asserting absolute uniqueness. The polite counterpart is くらいのものです.
