Grandma and grandpa (or gramma and grampa when said in a hurry).
You called one of your Grandmas “Grandpa”? Sounds like there’s a story there.
Of relevance to the OP: My family is from the NE, but “nanna” was already taken, since my paternal Great-Grandmother was still alive when we were kids, and that’s what we called her (I assume because that’s what my father called her). So my grandma was either “grandma” or “grammy”.
I had a Libby, not a name she ever went by (if you were close enough for first names she was Elizabeth) except for grandkids, she loathed becoming old and didn’t want us reminding her at every turn. My paternal grandmother who died when I was very young had apparently decided this was a fabulous idea and chose Betty to keep up (she was Elisabeth) but it never actually got a run.
Nana/Nan is what I hear most amongst the Aussie kids I work with. My partner is Jelly to her grandkids.
Maternal and Paternal, Ma Maw and Pa Paw (Pronounced Maw Paw and Paw Paw. Not sure why we spelled them like that; it was already established by the time I came along.
Dammit.
My paternal grandmother (whom I only met once when I was five), I forget.
My maternal grandmother was “Grammie,” mostly because (and I didn’t find this out until relatively recently) this is what I organically called her (apparently) when I was first old enough to speak. As the firstborn grandchild, it stuck.

My grandparents were “Grandma” and “Grandpa” with lastname used to differentiate when the need arose. Oddly, my maternal grandmother’s moniker has changed after her death. She’s now become Grandma [Grandpa’s nickname], which is a shortened version of their last name. No one is quite sure how that happened, but I don’t think she would have minded.
My own mother is Nonny to her grandkids. She was made a grandmother too young, she says, and didn’t want to be called Grandma. We just let it lie until my son named her during a babble stage. We were watching Much Ado About Nothing, he was sitting on her lap, and when the line, “With a hey, nonny, nonny!” was said, he started babbling “Nonny! Nonny!” and batting at her face. So Nonny it was. We didn’t find out until years later that it’s an Ethnic name for grandmothers.
My grandparents were grammy and grampy. Well, my maternal grandparents. My paternal grandmother died before I was born and my paternal grandfather was someone I only met a handful of times so I didn’t call him anything in particular.
I’m a Nana, my maternal grandmother was a Nana, but my mother was Grandma to all the kids. She really wanted to be called ‘Grandy’, but it just never seemed to take off.
(Edited to add). As noted by Thylacine, Nan or Nana’s prolly the most common in Australia.
Mamaw, and Papaw American South
I called my maternal grandmother Granny and my paternal grandmother Nan. I’m Australian.
I didn’t really type that
I had a Nanny and a Momsie. For your bonus, I had a Papaw and a Popsie. Memphis,Tennessee. Momsie and Popsie were from Nebraska and had that title long before we Southern grandkids were around.
Maternal: Nanny when we were young, Nan as we grew up. Her male counterpart was Poppy when we were young, Pop when we grew up.
Paternal: Grandma, always. Her male counterpart was Grandfather, always.
My kids call their Aussie maternal grandparents Nanny and Pa, and call their British paternal grandparents Granny and Grandpa, which I think was supposed to be Grandad but it didn’t work out that way.
Totally off-topic!
Hey Eliahna, about to send you an email about a weird family situation and might need some genealogical advice…stay tuned!
Maternal: Grandma and Grandpa
Paternal: Grandma as a child, then Grams when I got older and Poppy.
Grew up in East TN. My husband’s mother was Grandmother. My paternal grandmother was Grammaw. On my mother’s side her parents were Poppa and Mom. Everybody called her that—us, the extended family, the neighborhood (women her own age called her Mom) and at church. I don’t think many people knew her name was Mary or that, when young, her nickname was Molly.
We used to run the roads together. I miss her.
Maternal: Grandmother and Granddaddy.
Paternal: Grandma and Grandpa.
Maternal/maternal great grandmother: Granny.
I’m from Georgia, for many generations.
My husband, who is just as southern as I am, and born about 30 miles from me, five months earlier than me, called his grandparents Memaw and Pepaw, on both sides.
My kids call all of their grandfathers Papa (Firstname,) and their grandmothers are Grandma and Mimi.
Always ‘Nana’ (and Pop) in my family, who are from Suffolk in the east of England (British-style hick country). Gran/Granny and Grandad seem more popular amongst the average Brit.
