The invention discloses a cold-roll steel sheet texture measurement method which comprises the following steps: S1, treating the surface of a cold-roll steel sheet so as to obtain a test sample 1; S2,measuring the <111>//ND texture ratio within the maximum orientation deviation of 20 degrees so as to obtain a result A; S3, performing argon ion etching on a test sample 1 to be tested so as to obtain a test sample 2 to be tested; S4, detecting a surface argon ion etching depth T of the test sample 2 to be tested; and S5, measuring a <111>//ND texture ratio within the maximum orientation deviation of 20 degrees so as to obtain a result B, and repeating steps S3 to S5 till the quotient of the absolute value of BN-AN divided by AN is greater than or equal to 50%, thereby obtaining a final argon ion etching depth TN, that is, the depth of a cold-roll steel sheet surface texture. By adopting the method disclosed by the invention, the depth of a micro-grade characteristic texture of the surface layer of a cold-roll sheet that the crystal orientation has differences from that of the central part of the cold-roll sheet can be accurately measured.
