You can make burgers in whatever size you prefer:

Standard sizes are approximately:

If you use 2.6 lbs (1200 g) and make 5.3 oz (150 g) each, you'll get 8 burgers.
If you use 2.6 lbs (1200 g) and make 4.2 oz (120 g) each, you'll get 10 burgers.

✅ To make it clear:
• 4.2 oz (120 g) → thinner burger, cooks quickly
• 4.6–5.3 oz (130–150 g) → ideal standard (most common at home and in burger joints)
• 5.6–6.3 oz (160–180 g) → large / gourmet style
• 7 oz (200 g) or more → XL (super hearty 😅)

❌ Common mistakes
• Pressing down with the spatula
• Cooking on low heat
• Flipping too many times
• Using very lean meat (80/20 is better)
