Understanding Mylar Bag Sizes

Choosing the right mylar bag size is crucial for your product presentation and customer experience. Whether you’re packaging coffee, herbs, edibles, or specialty goods, the size you choose affects shelf appeal, portion control, and perceived value.

3.5g (⅛ oz) — 85 × 130mm

The 3.5g bag is the most popular size for single-serve portions, sample packs, and gift packaging. Compact enough for retail displays, large enough to showcase your brand design effectively. Ideal for new brands testing the market.

7g (¼ oz) — 100 × 150mm

The standard retail size. The 7g bag offers a balanced amount of product with plenty of surface area for branding. This is the go-to size for most retail environments and online stores.

14g (½ oz) — 120 × 180mm

Perfect for bulk retail and multi-serve portions. The 14g bag is popular with established brands selling larger quantities at a better value proposition. Great for repeat customers and loyalty-driven sales.

28g (1 oz) — 150 × 230mm

The wholesale size. Best for high-volume customers, trade accounts, and bulk distribution. Offers the best value per unit and maximum design real estate for premium branding.

How to Choose Your Size

Consider your target customer, pricing strategy, and shelf placement. Most brands start with 3.5g bags to test designs, then expand to larger sizes as demand grows. Our product configurator lets you select any size and see pricing update in real-time.
