Bob Ross is a famous painter who manages to spread his passion for painting to many artists. And many artists wish to paint the same as him.
The first step is to know what size of canvas does Bob Ross uses?
I will go straight to the answer.
Standard 18 “by 24 “stretched and double primed canvas
In this video, on 00:01:05 you can hear what size canvas does Bob Ross uses on his tutorials.
What is a stretched canvas? Name by itself explains a lot of things, but let’s go deeper.
On the market, you can find a stretched canvas stretched over the wooden frame, this type of canvas Bob Ross used. The great thing about them is that you have a stretched surface for painting, which is crucial for painting.
And when the painting is finished, it is ready for display; you can immediately mount it on the wall!
Bob Ross canvas also choose double primed canvas, so what that mean?
It means that you can paint on canvas without priming it before use, but it’s recommended to re-gesso all new canvases. Even those that are double primed!
The reason is that you don’t know-how is made your canvas. Most manufacturers use different types of primers/gesso. Because of that, you can’t be sure what is your base of the canvas.
If your surface is not adequately prepared, it can significantly impact how your oils will interact with the canvas’s bad primed surface.
So put a couple of layers of gesso, and you are ready to roll.
I know that Bob Ross didn’t re-gesso his canvases. Mostly he put white paint to make the canvas wet and smooth for better control. That is probably because his canvases were well primed and made especially for him.
