Size of Rollers

I’m really hoping to achieve the same effect without using magnetic rollers. Would foam rollers be able to give me a similar result? And if so, what size should the foam rollers be? Thank you so much for your help. I’d truly appreciate a response!
You can absolutely achieve a similar look on long hair using sponge (foam) rollers, but you’ll need to opt for extra-large foam rollers to compensate for the difference in curl tension. One of the biggest advantages of sponge rollers is that they are much more comfortable to sleep in compared to traditional magnetic or plastic rollers. And because of their soft, flexible texture, sponge rollers often create subtle variations in the curls, which can result in a more natural, lived-in style rather than uniform ringlets.
It’s important to note that sponge rollers typically produce a slightly tighter curl than magnetic rollers of the same size. To achieve a comparable result, you may need to go up in size when switching from plastic/magnetic rollers to foam rollers. For example, if you would normally use a 1-1/2 inch magnetic roller, you might want to try a 1-3/4 inch or even 2-inch sponge roller to get a similar level of softness and volume. Testing different sizes can help you fine-tune the look to your preference.
