There are dozens of different species of small parrot that are called parakeets. The one most commonly kept as a pet is the budgerigar, also known as a budgie. Wild budgies are usually about 7 inches (18 cm) from beak to the tip of their tailfeathers. Captive budgies vary in size, with English/show type budgies being larger than those found in the pet trade in North America.

Wild budgerigars weigh 1.1-1.4 oz.
A full grown parakeet is usually no more than six inches tall. Make sure not to confuse a parakeet wit a budgerigar (budgie for short), which looks very similar to a parakeet, but is not the same exact thing as a parakeet and are taller than the average parakeet.

Height is an attribute: it can be measured using the metric, customary or made-up system. An example of the last one is "X is twice as long as my wife's pet, Fluffy". If you don't know what kind of creature Fluffy is then you know next to nothing about X's length. And, incidentally, Fluffy was named with the same sense of humour (!) as the three headed dog in Harry Potter and the Chamber of Secrets.

A customary unit that can measure a telephone is inches or centimeters, typically measuring the height, width, and depth of the device.
It would be alright as long as the parakeet does not feel sick or frightened at all. If the y feel frightened then the parakeet might die.
