Bloks Review: Big Bricks vs Small Bricks Compared
Here is the bottom line first: the two Bloks lines do different jobs. For ages 3-6, buy the big-brick range — safe and easy to build. For ages 6+ or adults who want faithful detail, buy the small-brick range, where mecha and space themes live. The two lines do not share parts, so do not buy across them expecting to mix pieces.
Among Chinese brick brands, Bloks is one you cannot skip. It broke into the young-kid market with big bricks, then moved into teen and adult territory with small bricks, and the two product lines sit in very different places. Plenty of first-time buyers stall on the same question: which line should I actually get? This Bloks review lays out both.
1. Brand positioning and product lines
Bloks positions itself as an all-ages Chinese building brand, and its core selling point is the big brick: larger than a standard brick, easy to click, hard to swallow, which makes it a natural first brick set for young children. In recent years the company added a small-brick series with parts sized to the mainstream standard, covering mecha, space and city themes, aimed at upper-primary kids through adult builders. Put simply, big bricks sell safe early learning, small bricks sell fine detail.
2. Representative sets
On the big-brick side, the buildable cars, zoo and farm themes are the classics: rounded parts, bright colors, few but large pieces, buildable by a two- or three-year-old working alone. There are also licensed IP preschool ranges with high recognition value that kids take to quickly. On the small-brick side, mecha and space are the most representative: mecha sets have plenty of articulated joints and sharp silhouettes, while the space sets reproduce rocket and space-station structure. Detail and play value are noticeably more hardcore, and the audience skews older.
3. Build experience and quality
Experience differs sharply between the lines. Big bricks are close to zero-threshold: large parts, moderate clutch that a child can pull apart and press home, and rounded corners that do not hurt hands. Safety is the biggest advantage. The downside is cartoonish shapes and simple detail — an adult will find it thin. Small bricks clutch tighter and carry finer parts, and mecha articulation and scene accuracy step up clearly, so a build feels like a model. For a young child, though, the parts are small and the steps are many, so it demands focus and patience.
4. Value for money and who should buy
On price, big bricks run slightly high for the piece count and play value, but they win on durability and rebuildability — one set lasts a long time, which suits safety-first families with young kids. Small bricks sit closer to mainstream brick pricing, and the big mecha and space sets are genuinely good value by piece count, making them a fit for students and adults who enjoy detailed building. If a child is just meeting bricks, take the big-brick line without hesitating. Once they are in primary school, or if you want to build yourself, the small-brick series is the better match.
5. Pros and cons
To sum up this Bloks review: the big-brick strengths are safe, easy building, rounded and durable parts, and strong early-learning value; the weaknesses are simple detail and limited adult appeal. The small-brick strengths are high accuracy, hardcore subject matter and a real sense of achievement; the weakness is that the parts are too small for young kids. Each line has a clear audience, so choose by age and purpose and you cannot go far wrong. If you want freer building beyond both lines, BrickPlan carries plenty of standard-brick MOC instructions, and paired with loose parts they open up a much bigger world — the two hobbies double the fun together.
FAQ
Q: What is the difference between Bloks big bricks and small bricks? A: Big bricks are larger with rounded corners, aimed at ages 3-6 for safety and easy handling. Small bricks follow mainstream sizing with mecha and space themes, aimed at upper-primary and above, and chase accurate detail.
Q: What age is Bloks suitable for? A: The big-brick line fits ages 3-6, where a child can finish simple models alone. The small-brick line is best from 6 and up, with independent building going more smoothly after 8; younger builders need a parent reading the instructions alongside them.
Q: Is the Bloks small-brick line worth it for adult builders? A: Worth a try, especially the mecha and space themes, which have plenty of articulated joints and solid accuracy, with most sets running 100-400 yuan. Part tolerance and clutch feel still trail the top-tier brands by a clear margin.
Q: First Bloks purchase — big bricks or small bricks? A: Decide by age. For a 3-6 year old, pick a big-brick buildable car or zoo theme. For yourself or a child 6+, pick small bricks, starting with a 200-500 piece set to test the feel before expanding the line.
