When developing custom swimwear, fabric composition is only part of the decision. Gewicht van de stof, measured in GSM (grams per square meter), also affects how your swimwear looks, feels and performs.
A lightweight fabric may create a softer and more flexible garment, while a heavier fabric can provide greater coverage, structure and durability.
But there is no single GSM that is best for every swimwear product.
The right fabric weight depends on your design, doelgroep, garment construction, voering, intended use and required performance.
At Makeswimwear, we help brands evaluate fabric weight together with stretch, herstel, composition and construction before bulk production.
GSM means grams per square meter.
It indicates the weight of the fabric rather than simply describing whether the fabric is “thick” or “thin.”
Two fabrics can have similar compositions but different GSM values and therefore provide different:
For swimwear buyers, GSM should therefore be considered as part of the complete fabric specification.
Lower-GSM fabrics may be suitable when you want:
Echter, very lightweight fabric may require additional attention to coverage, opacity, lining and durability.
A medium-weight construction is often a practical choice for many commercial swimwear collections.
It can provide a balance between:
This makes it useful for many bikinis, one-piece swimsuits and fashion collections.
Higher-GSM fabrics can provide:
They may be appropriate for selected premium, shaping or performance applications.
Echter, heavier does not automatically mean better.
| Swimwear Application | Fabric Weight Consideration |
|---|---|
| Fashion bikini | Lightweight to medium |
| Premium bikini | Medium to heavier |
| One-piece swimsuit | Medium to heavier |
| Sports swimwear | Performance-dependent |
| Competition swimwear | Performance and construction dependent |
| Badkleding voor resorts | Comfort and appearance focused |
| Kids’ swimwear | Coverage, comfort and durability |
| Shaping swimwear | Structure and recovery are important |
These are development guidelines rather than fixed specifications. The final GSM should be confirmed through sampling and testing.
A common sourcing mistake is to assume that heavier fabric is automatically higher quality.
It is not.
Fabric performance also depends on:
A lighter fabric with excellent recovery may outperform a heavier fabric with poor elasticity.
Instead of simply telling a manufacturer:
“I need thick swimwear fabric.”
Give the factory a complete specification.
Consider:
This creates a much clearer development brief.
At Makeswimwear, fabric selection is evaluated together with the actual garment design.
We can help review:
The goal is not simply to choose a number. It is to choose a fabric specification that works for your finished product.
Not necessarily. Higher GSM can provide more coverage and structure, but the best weight depends on the product and required performance.
Ja. Fabric weight can affect material consumption and cost, but composition, construction, finishing and other specifications also influence the final price.
Not necessarily. Different designs may require different combinations of weight, strekken, recovery and lining.
For suitable production volumes, custom fabric development may be possible depending on composition, construction and supplier requirements.
Tell us your swimwear design, target market and performance requirements. We can help you evaluate fabric weight and develop samples before bulk production.
