See the height requirement for the post of constable is dependent on the state Government you are applying for. For example, In westbengal police service, the height requirement for the post of constable is 160cm for MALE but for AP its around 167cm. Now for GD constable its 170 cm for MALE. So you need to specify which exam you are appearing in and we can provide you more specific answer.
