Poetry Tiles Essential Kit – 797 Word Magnets for Fridge Poems and Silly Magnetic Messages – Get Creative, Express Yourself, and Make Others Laugh at Your Witty Words – .375" Tall Tiles

Will this work on any magnet surface or just the fridge?

Poetry Tiles work on most metal surfaces - not just the fridge. You could also put them on a whiteboard/message board.

Are these magnets strong enough to hold up pictures?

Using small pictures or lots of magnets can work, but if you're planning to put up large pictures or expecting to only use a few magnets per picture, that probably won't work. Each tile is strong enough to magnetize its own weight but not much more than that.

Are these similar in size to other brands of magnetic poem sets for mixing things up?

The size (.375" tall) is the same as most magnetic poem products. Fonts may differ if you choose sets from different brands.

Are there repeat words or multiple copies of common words?

Yes, the kit includes multiple copies of useful words. There are a few copies of most pronouns, connecting words (like to, the, and, but, is, am, etc), and word endings (like -s, -ed, -ly, etc).
