5 1/4
The stock front door speakers on 97- 01 lumina are 5.25 round but the depth of the speaker is an important dimension since the speaker is front mounted in an enclosure which is mounted to the door. I replaced my stock speakers with Sony Xplod model XS-R1342. Any 8 ohm model speaker with similar dimensions will work.
