Abinash,
You can use the method which are used in the competitions where people practice according to the area they can have. Its not necessary that you need to have a big place to practice archery as you can practice that in your own garden area or backyard.

Try to practice in a length area rather than breath as it will give you a chance of having to practice with bigger area. In competition the areas are big some what like -
Long range (180 yards / 165 m for the men and 140 yards / 128 m for women; there are shorter distances for juniors depending on age) into a group of concentric circular scoring zones on the ground surrounding a marker flag.

The flag is 12 inches (30 cm) square and is fixed to a stick. The flag should be as near to the ground as is practicable. Archers shoot 'ends' of six arrows then, when given the signal to do so, archers proceed to the target area.

it depends upon the person who whats to practice,taking into consideration that in what event he needs practice like 10meter ,20meter,etc.
BASIC MINIMAL SPACE should be of 10 meter LENTH and 2meter BREATH.

Well Abinash nice question,many dont know about this game and regulation and what minimum requirement space needed for it,after searching from net i came to know that 15 yards reqd if you are going to shoot a compound bow. That is the very minimum. Markers from 10 to 35 or 40 every 5 feet would be ideal for practice.
