# What size of lv_style_set_text_letter_space does?

## Description

I am using lv_style_set_text_letter_space (value) to add the space between letters.
Does the size of space rely on font size?( the larger the font size, the larger the spacing )

or the size of space is the number of lcd dot (pixel) set by value? ( no matter how big the font size is, the spacing won’t change )

Below is the example if set value is the lcd dot
lv_style_set_text_letter_space (3)

`lv_style_set_text_letter_space` should simply insert the given number of pixels between every letter.

So, no matter how big the font size is, the spacing won’t change, is it right?

lv_style_set_text_letter_space( numbers of pixels ) , is my thought right?

Yes, the font size remains.
But you can easily try it out.

What do you mean?

What is unclear?

Yes, the font size remains.

I just don’t understand what this sentence’s mean.
Did you mean the space ( numbers of pixels ) does not change ?

E.g. letter `k` will look the same regardless to the letter space property. Only the space between the letters will change.

Why the space is changed?
I thought that the space is the number of pixels of lcd, and the pixel size is fixed.
Therefore, when the font size change, the K letter also changed, but the space between K & K is not changed.
Sorry, but could you explain more about that.
E.g, when I set space as 3 pixels
lv_style_set_text_letter_space (3)
this space will be fixed although font size changed
