If you’ve spent any time on the gaming side of the internet over the last decade, you’ve definitely run into the Kurzawa family. Specifically, the powerhouse that is Karina Kurzawa. Whether you know her as GamerGirl, the older half of the legendary SIS vs BRO duo, or just that girl who somehow made Roblox look like a professional sport, she's been a digital staple for years.
But lately, people are scratching their heads. They’re looking at these old videos of a tiny kid and then seeing her current Instagram posts and going, "Wait, how old is Karina Kurzawa now?"
It’s a fair question. She basically grew up in front of a lens.
The Short Answer: How Old Is Karina Kurzawa?
Let's cut right to the chase because honestly, the internet loves to make this more complicated than it is. Karina Kurzawa was born on March 23, 2007.
As of right now, in early 2026, Karina is 18 years old. She’ll be turning 19 this March.

It’s a bit of a trip for fans who remember her starting out when she was just seven or eight. Back then, it was all DIY crafts and toy reviews on her FUNwithKARINA channel. She was this energetic kid in Canada who eventually moved to Spain because—get this—she was actually allergic to the cold. Not just "I hate winter" allergic, but like, medically needed a warmer climate. That move to Spain was a massive turning point for her and her brother Ronald, setting the stage for the massive success of their joint channel.
Why the Age Confusion Happens
The reason people are constantly asking about her age is that her "internet era" has lasted forever. Most creators flame out after two years. Karina has been around for over ten.
When you have a library of videos spanning from age 7 to 18, the YouTube algorithm often serves up a mix of both. You might watch a video of her at 12 years old reacting to a "try not to laugh" challenge, and then see a TikTok of her at 18 looking like a completely different person.
The SIS vs BRO "Retirement"
Another reason for the sudden spike in curiosity is the shift in her content. A few years back, the SIS vs BRO channel—which had over 14 million subscribers—pretty much stopped. Fans were devastated. There were rumors, "downfall" documentaries on YouTube, and all sorts of drama-baiting.

The reality? They just grew up.
Think about it. Would you want to do "sibling challenges" with your brother for the rest of your life when you're entering your late teens? Probably not. Karina started prioritizing her own brand, GamerGirl, and her personal lifestyle content. She shifted from being "the sister" to being an individual creator. This transition from "child star" to "adult influencer" always triggers a wave of "Wait, how old is she now?" searches.
A Timeline of the Karina Kurzawa Era
To understand how she got here, you kinda have to look at the milestones. It wasn't just luck; it was a decade of daily grinding.
- 2015: The start. She launches her first YouTube channel. She’s just a kid in Canada doing what kids do—playing with toys and making crafts.
- 2016: The Spanish Move. The family moves to Spain. This is when SIS vs BRO and GamerGirl really take off. The visuals get better, the energy is higher, and the subscriber count starts hitting millions.
- 2018-2021: The Peak. This was the golden age of Minecraft and Roblox videos. If you had a younger sibling during this time, you definitely heard Karina’s voice coming from their iPad at full volume.
- 2022-2024: The Pivot. The joint channel slows down. Karina starts posting more about her life, fashion, and travel. She graduates from Sotogrande International School in Spain.
- 2025-2026: The New Chapter. She’s officially an adult. She’s navigating the world of professional streaming and brand deals on her own terms.
What Most People Get Wrong About Her
People often think she's younger than she is because she has such a "young" fan base. But Karina has been legally an adult for a while now. She’s managed to keep a relatively clean image, which is rare for someone who grew up with that much money and fame.

Speaking of money—people often ask if she’s actually a millionaire. While internet net worth sites are usually full of it, it’s no secret she’s done incredibly well. Some estimates put her at $4 million to $14 million, though she’s never confirmed a specific number. Between the merchandise, the AdSense from billions of views, and the brand deals, she’s set for life before she even hits 20.
Why She Still Matters in 2026
The influencer world is fickle. Most people from the 2016 era of YouTube are completely irrelevant now. So why is everyone still asking about Karina?
- Nostalgia: An entire generation of Gen Z and Gen Alpha grew up with her. She’s like their digital big sister.
- Consistency: Even when she took breaks, she never fully vanished. She adapted. She went from YouTube to TikTok to Instagram seamlessly.
- The "GamerGirl" Brand: She was one of the first young girls to really dominate the Roblox/Minecraft space, proving that gaming wasn't just a "boys' club" on YouTube.
Moving Forward with the Kurzawas
If you're looking for her nowadays, don't expect the same high-pitched "Hey guys!" intro from ten years ago. She’s more laid back. Her Instagram (@kurzawa_karina) is a mix of high-end travel and behind-the-scenes life in Spain and abroad.
Actionable Insights for Fans and Creators:
- Respect the Pivot: If you're a fan, realize that creators have to evolve. If she kept making the same videos she made at age 10, she’d be miserable.
- Look at the Blueprint: For aspiring creators, Karina is a masterclass in "brand safety." She built a massive empire without resorting to the typical "clout-chasing" drama that ruins most careers.
- Check the Dates: Always look at the upload date of a video before wondering why she looks so young. She’s a 2007 baby through and through.
The "child star" curse is real, but Karina Kurzawa seems to have dodged it. By knowing when to walk away from her biggest channel and focus on herself, she’s successfully navigated the weirdest transition a human can make: growing up in public.
