Choosing between 6oz and 8oz jars can be tricky. Order the wrong size, and you risk wasted packaging or unhappy customers. In this article, I’ll compare both options so cosmetic brands and manufacturers can make the right choice.
The main difference between 6oz and 8oz plastic jars is capacity: 6oz holds around 180ml, while 8oz holds about 240ml. A 6oz jar is slightly smaller and often used for mid-sized cosmetics like face masks or scrubs. An 8oz jar is considered “full size,” ideal for body butters, creams, or bath products.
Now that we know the key difference, let’s explore their dimensions, applications, and market implications through detailed comparisons.
Outline
Dimensions: 6oz vs 8oz Plastic Jars
When buyers evaluate packaging, size specifications are critical. The table below shows the average differences in dimensions and materials.
| Feature | 6oz Plastic Jar | 8oz Plastic Jar |
| Capacity (ml) | ~180–200 ml | ~230–250 ml |
| Typical Diameter | 2.8–3.0 inches (7.1–7.6 cm) | 3.0–3.5 inches (7.6–8.9 cm) |
| Typical Height | 2.3–2.7 inches (5.8–6.8 cm) | 2.7–3.5 inches (6.8–8.9 cm) |
| Material Options | PET, PP, Double-Wall | PET, PP, Double-Wall |
| Weight | Lighter, saves shipping cost | Slightly heavier, higher freight cost |
👉 As shown above, the difference isn’t just in capacity—8oz jars occupy more space, which impacts shipping and shelf display.
Product Applications
Different cosmetic products perform better in different jar sizes. The table illustrates which type of jar suits which kind of product.
| Product Type | Best Fit: 6oz | Best Fit: 8oz |
| Face Masks | ✔ Ideal for premium clay/gel masks | ✖ Too large for concentrated masks |
| Scrubs (Sugar/Salt) | ✔ Smaller indulgent jars | ✔ Larger jars for daily/family use |
| Body Creams | ✔ Mid-range body or hand creams | ✔ Full-size body butters and lotions |
| Hair Masks | ✔ Boutique salon treatments | ✔ At-home tubs with multiple uses |
| Bath Salts | ✖ Usually too small | ✔ Large capacity packaging |
👉 This shows that 6oz jars are perfect for premium and boutique lines, while 8oz jars are ideal for mass-market or everyday skincare products.
Consumer Perception
Packaging size also affects how customers perceive value and exclusivity.
| Aspect | 6oz Plastic Jar | 8oz Plastic Jar |
| Market Positioning | Boutique, premium, mid-size option | Standard, full-size, mass market |
| Customer Feel | “Special treat” or gift-worthy | “Value size” with more product |
| Portability | Travel-friendly, compact | Bulkier, designed for home use |
| Branding Effect | Suggests exclusivity | Suggests affordability & generosity |
👉 In short, 6oz communicates sophistication, while 8oz communicates value. Both can be powerful, depending on your brand strategy.
Cost & Logistics
From a B2B perspective, cost and efficiency are as important as consumer appeal.
| Factor | 6oz Plastic Jar | 8oz Plastic Jar |
| Unit Price (Wholesale) | ~$0.35–$0.50 per jar | ~$0.40–$0.70 per jar |
| Production Cost | Slightly cheaper to produce | Higher material usage |
| Shipping Efficiency | More jars per carton or pallet | Fewer jars, higher freight cost |
| Retail Price Strategy | Can justify premium pricing | Attractive price-per-ounce for consumers |
👉 If you’re aiming for cost savings and boutique sales, 6oz is smarter. For competitive value-per-ounce pricing, 8oz is the better choice.

Final Thoughts
Both 6oz and 8oz plastic jars serve important roles in cosmetics. 6oz jars emphasize boutique quality and exclusivity, while 8oz jars highlight value and practicality. The right choice depends on your product’s positioning and your target market’s expectations.
