UTF-8 glyphs are too small

I have been setting up my new terminal on both of my MacBooks Pro and I noticed that UTF-8 glyphs are way smaller on one of them. This holds true in every application and I can't find the setting that differs between the two laptops so I can get the big glyphs on both. Here are two pictures showing the difference: I thought it would be related to the locale variables but no: LANG="fr_FR.UTF-8" and LC_ALL="fr_FR.UTF-8". Any help is welcome! PS: I work on Mac OS Sierra
