personally i had a really hard time trying to make dividers so i'm making this to hopefully help others who may be having the same problems as me.

1. Programs

i like to use clip studio paint since that is what i have but there are other free options too like: Photopea (free, browser), Canva (free, browser),IBIS Paint (free, ios/android), ect...

2. Canvas Sizes

this is where i struggled the most since it can be hard to judge how something will look in a post vs how it looks when you're making it. i put together some "guideline" dividers so its easier to see how things will look:

^ small divider 2000 x 40px ( good for pixel art )

^ medium divider 2000 x 100px (good for small doodles)

^ large/ medium divider 2000 x 140px (small text and drawings)

^ large divider 3000 x 225px ( good for titles )

obviously you don't have to follow these exactly but they are a good reference for what looks good at different sizes

3. Saving

the way that you save your drawings will affect how they look if you want parts to be "clear/ see through" make sure to save in .png these files may be a little bit bigger but they will keep any transparent parts of your divider / drawing.

^ a good example of this is my star divider

if you're ok with having no transparent parts/ a solid colour, pattern divider you can save in .jpg these files are smaller than .png so are good if you don't have a lot of space on your device. All of the above "size example" dividers are .jpg so they don't have any transparent parts. [Side note: if you have transparent parts in your drawing but save it in .jpg they will become white]
