Recently, there has been a new trend of smaller keyboards because they consume lesser real estate.
These come in various form factors such as Tenkeyless (TKL), 60%, 65%, 80%, 96% keyboards.
100% - These are our regular full size keyboards. This one is my older and the best in this category Das Keyboard Professional
65% - These do not have function keys and neither the numpad. This one is Ducky one 2 SF
TKL or 80% - Tenkeyless. They do not have numpad i.e. 10 keys less. One of the best is Ducky one 2 Skyline TKL
60% - Similar to 65%, but these get rid of arrow keys too. This is Ducky one 2 Mini skyline blue
96% - These essentially have all keys, but with compact design. Below is my current Keychron k4
Best resources for mechanical keyboards in India:
Reddit - Mechanical Keyboards India - A place to discuss about mechanical keyboards in India
Meckeys - Currently, the best place to buy mechanical keyboards in India
Keychron.in - You can order keychron keyboards in India from here. Though they have been out of stock due to COVID for quite some time.
Reddit - Mechanical Keyboards - A best place if you want to assemble your own keyboard. Not for the purchasers.
There are other places as Amazon, AliExpress etc, but I don’t recommend due to the higher prices because of custom duty imports.
Collecting and trying out various keyboards is slowly becoming one of my hobbies though a very expensive one :)
