33-34mm is a narrow measurement, but yours looks wider than that in the photo. Are you missing teeth on your right side?

@paperbag No I don't have any missing teeth and I don't have any Wisdom teeth erupting. Plus I have to mention the fact that I have gaps in my front teeth and never had orthodontics in my life.

This is my smile in the front view 

@basim Your palate is definitely wider than 34 mm, looks good. I know someone who has those same gaps and didn't have orthodontics either, he looks a lot like you. Definitely better to have additional space than not enough.

What his name. I would like to know him

@basim I won't give his name out, he's an old friend. He doesn't know anything about Orthotropics and wouldn't be able to help you.

Ok. But what do you think is my IMW if it's not 34 mm. What's your estimation 

you're gonna have to find something to measure it properly

I do wonder. Does Mewing closes the gaps in my teeth as I know my palate will countiune to expand and my gaps will get larger due to this effect. I hope I don't my palate expand too much where I have Ronald Eads gaps post MSE treatment.

I just measured my IMW by chewing on a paper towel and my estimation is around 38-39 mm . Which could explain that I can mew easily and my tougue is slight touching the molars when I bring the back third. Plus I do have proclined Cannies and incisors.

Gotta agree with @PaperBag because your palate indeed looks wider than 33-34mm. There's a guide on measuring the IMW with cardboard in this forum, you should look it up.
