How to Adjust the Line Spacing in Adobe InDesign

What is the equivalent of 1.5nk line spacing in Word file in InDesign?

I want to set double spacing so how much Pt I should choose

How do you even out each character space without having to do kerning? Example business card with two lines of numbers and the numbers don't line up even, because the character had different widths?

Simple and clear explanation. Thank you.

Dear video producer: the actual pronunciation of "leading" is "ledding". That's because the space between the lines was achieved using pieces of lead of different heights in earlier times up until the appearance of the modern printing press. 😉

Hey there thank you for this! Can you please help me figure out what they mean in brand guidelines that say 140% line height??

Superb Teaching
