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.

How to Choose the Right Bag Size?

Step 1 : Define the Use Case and Target Audience

First, clarify who will use the bag and how it will be used:

  • A mini clutch for parties?
  • A medium-sized work tote for professionals?
  • A large duffel bag for weekend getaways?
  • An oversized storage bag for home organization?

Step 2 : Translate into Size Requirements

We convert these needs into clear dimensions and capacity specifications:

  • Internal size requirements (e.g., fits a 13-inch laptop or specific makeup set)
  • External size constraints (e.g., airline cabin dimensions)
  • Weight capacity and load requirements

Step 3 : Prototyping and Size Validation

We create samples and test:

  • Actual item compatibility (laptops, bottles, diapers, makeup bags, etc.)
  • Comfort levels for small/medium/large sizes when worn
  • Visual proportion and alignment with brand identity

Step 4 : Final Sizing Chart and Mass Production

Upon confirming dimensions, we will:

  • Finalize the bag sizing chart and specification parameters
  • Standardize patterns for mass production
  • Establish clear quality control tolerances for each custom size

FAQ

Can you match our existing size system (S/M/L)?

Yes. We can take your existing bag dimensions and convert them into a clear size chart, then develop new styles that follow the same logic.

Can you design a full mini / medium / large range from scratch?

Yes. Give us your target category (handbag, tote, backpack, travel bag, storage bag) and budget. We’ll propose custom bag sizes, materials and structures.

How precise are your size tolerances?

For most projects, we apply strict tolerances (e.g. ±0.5–1.0 cm) depending on material and construction, so your bag dimensions remain consistent across orders.

Can you adjust sizes for different markets?

Yes. We can create EU / US / Asia versions with slight size adjustments while sharing the same design.
