# aptible services:autoscaling_policy:set

Sets the sizing (autoscaling) policy for a service. This is not incremental, all arguments must be sent at once or they will be set to defaults. Also aliased to `services:sizing_policy:set`.

For more information, see the [Autoscaling documentation](/docs/core-concepts/scaling/app-scaling)
