Movie Ratings Explained: What PG, PG-13, R, and NC-17 Really Mean

PG, PG-13, R and NC-17. You’ve seen them everywhere: on cinema posters, streaming platforms, and even Netflix thumbnails, and wondered what they mean.  They are supposed to tell you whether a movie is suitable for children or adults only. But many people don’t know what they mean. For most of us, it’s a mix of guesswork. 

We assume PG is kid-friendly, R is probably wild, and PG-13 is suitable for thirteen-year-olds and above. Yet every so often, a PG-13 movie surprises us with a scandalous scene, or a film labelled R feels tame compared to what we’ve seen on Nollywood screens.

That’s when it hits you: these movie ratings clearly mean something, but what exactly?

PG stands for Parental Guidance, and it means exactly that. It’s a gentle warning that a film may not be suitable for very young children without an adult present.

Think of movies like Finding Nemo, The Lion King, The Wedding Party, Chief Daddy or Encanto. They’re fun and family-friendly but still touch on emotional or intense moments that might be confusing for very young viewers (yes, Mufasa’s death counts).

In Nigeria, though, we often assume “if it’s animated, it’s for kids.” Not always. Some PG-rated films tackle deeper ideas like loss, fear, or even mild language that may scar a six-year-old for life. 

A little parental presence never hurts. That way, you know what is and what is not ideal for your kid to watch.

PG-13 stands for parents strongly cautioned. This means some material may be inappropriate for children under 13.  It’s basically saying, “It’s not too wild, but maybe keep an eye on it.”

Movies like King of Boys (the first part), Sugar Rush, Black Panther, Doctor Strange, or Spider-Man: No Way Home fall here. 

These films have intense drama, mild violence, or suggestive themes, the kind that’s gripping for teens and adults but might fly over a child’s head.

But here’s the irony: many parents are fine with blood and explosions, yet gasp at one on-screen kiss. So PG-13 in Nigeria often translates to “don’t watch this one with mummy and daddy in the room.”

But really, mummy and daddy should be in the room.

R stands for Restricted, meaning no one under 17 should watch without a parent or guardian.

R-rated films often include strong language, violence, sexual content, and adult themes that are meant for mature audiences. Think King of Boys: The Return of the King, Omo Ghetto: The Saga, Citation, John Wick, Deadpool, or The Wolf of Wall Street.

It’s not about being “moral police”. It’s about recognising that some films aren’t made for every audience. They explore darker, heavier ideas. Some have brilliant storytelling with a sprinkle of chaos.

Streaming platforms make them accessible, but the rating reminds viewers that the content is heavy.

NC-17 means absolutely no one under 18 is allowed, even with a parent present. It’s reserved for films with explicit sexual content or extreme violence.

These films rarely make it to mainstream cinemas anywhere, and definitely not in Nigeria. Our censors won’t even blink twice before banning them.

NC-17 is rare, and in Nigeria, it’s almost non-existent in mainstream cinemas.

Globally, movie ratings are issued by the Motion Picture Association (MPA). They decided whether a film is suitable for children, teens, or adults. 

They look out for things like language, violence, nudity, and drug use.

In Nigeria, the National Film and Video Censors Board (NFVCB) reviews and classifies every film before it hits cinemas or streaming platforms.

With streaming and uncensored TikTok movie edits, anyone can access anything. Age gates and parental controls are easy to skip. But that makes media awareness more important than ever. 

Whether you’re a parent, older sibling, or just a curious viewer, understanding ratings helps you protect your mind and your mood.

Movies aren’t just entertainment. They shape how we think, love, and process the world. We often rely on vibes more than official labels. But movie ratings exist for a reason.

They help you make informed choices. Because while you might shrug off a violent scene, your younger sibling could stay awake all night because of it.
