The Reliable Custom Bag Size Manufacturer in China
Custom Bag Size – From Concept to Production-Ready Dimensions
At FY Bag Factory, we see size not as a measurement — but as a function of design. From compact mini purses to oversized travel duffles, every dimension defines how a bag interacts with the human body, how it carries weight, and how it reflects the user’s lifestyle. Our OEM & ODM production system is built on precision pattern scaling, ergonomic balance, and volume-optimized structure, ensuring each size delivers both aesthetic harmony and real-world performance.
For Brands, “small”, “medium” and “large” are not enough.We also should to know: exact dimensions, capacity, and use scenario.

Clear positioning
mini bag / small purse → impulse buy, gifting, trending item
medium tote / everyday bag → core daily seller
large bag / weekender duffle → high-ticket travel & storage piece
