You try and pass the pencil test without leaning back and holding your breath.

Measuring free sag. You will need a helper or 2.

Lift the bike so that the rear suspension is not supporting the weight of the bike. Measure between a point on the swingarm (usually the rear axle or end of swingarm) to a point on the frame (I try to use a point such that the measurement is close to verticle). Lets call this measurement A. With the rear wheel supporting the weight of the bike, push down on the rear of the bike and let it return. Take a measurement using the same points as before. Call this measurement B. Lift up on the rear of the bike and let it drop on its own. Repeat the measurement, call this C. Take an average of B and C ; (B+C)/2. subtract this average from A. This will be the free sag.

Around 5 to 10 mm is a good starting point.
