Suta Goswami says:
The Brahma Purana consists of ten thousand verses, the Padma Purana of fifty-five thousand, Sri Visnu Purana of twenty-three thousand, the Siva Purana of twenty-four thousand and Srimad-Bhagavatam of eighteen thousand. The Narada Purana has twenty-five thousand verses, the Markandeya Purana nine thousand, the Agni Purana fifteen thousand four hundred, the Bhavisya Purana fourteen thousand five hundred, the Brahma-vaivarta Purana eighteen thousand and the Linga Purana eleven thousand. The Varaha Purana contains twenty-four thousand verses, the Skanda Purana eighty-one thousand one hundred, the Vamana Purana ten thousand, the Kurma Purana seventeen thousand, the Matsya Purana fourteen thousand, the Garuda Purana nineteen thousand and the Brahmanda Purana twelve thousand. Thus the total number of verses in all the Puranas is four hundred thousand. Eighteen thousand of these, once again, belong to the beautiful Bhagavatam. —SB 12.13.4-9
