Here are few simple tips to select a stabilizer:

Check the voltage, current & power rating of the device. It is written on the specification sticker near power socket else check the user manual.
In India standard service voltage will be 230VAC, 50 Hz.
To get the maximum power - Multiply "230 x Max rated Current" of all the equipment that are to be connected to the stabilizer. Add a 20-25% safety margin to arrive at stabilizer rating. If you have plans to add more devices later, you can keep buffer for them.
You should also consider the surge current which flows when you switch on the device.
In case the Voltage Stabilizer has a rating in watts also, assume a power factor of 0.8 (W=V*A*pf).

The most important thing is to know the nature of the load connected to the stabilizer. First you must note down the power (or Watts) for all the appliances that will be connected to a stabilizer. The sum total of the power consumption (or Watts) will give you the load on the stabilizer in watts. But most stabilizer sizes are in VA (Volt Ampere) or kVA (kilo Volt Ampere which is equal to 1000 Volt Ampere). Although to get the actual VA (or Volt Ampere) from Watts (W) you will have to do some measurements, but to give a rough approximation, you can increase the Watts value by 20% to get the approximate VA size that you may need.

So for e.g. if sum of Watts connected to your stabilizer is 1000 then you can take a 1200 VA or 1.2 kVA stabilizer. (Please note that 20% is suitable for residential systems and may not work in industries if your power factor is bad).

Usually a stabilizer comes with different working ranges (working range is the voltage range in which the stabilizer operates/stabilizes the input utility voltage and provides a desirable output voltage). It's important to choose your stabilizer suiting the voltage fluctuations in your locality.

Make an idea of the level of power fluctuations that are common in your location. (E.g. extremely low/high voltage areas, moderate high/low voltage area etc.). You have to choose the working range of your stabilizers that will address the demands of your location. For instance, you might need to choose the stabilizer with a wide working range, if your location experiences extremely low/high voltage fluctuations.Type your paragraph here.
