Homemade Bread Weight
A standard 3-cup flour recipe makes a 21-25 oz (600-700g) loaf. Bread loses 10-15% weight during baking from water evaporation. A 700g dough becomes about 600-630g baked. Wetter doughs (ciabatta, high-hydration sourdough) shrink up to 20%.
Bread Math for Recipes
1 lb (454g) = 16-18 standard slices = ~80% of a standard loaf. French toast or bread pudding: 12-16 slices (12-16 oz / 350-450g). Breadcrumbs: 1 slice yields ~1/3 cup fresh / 1/4 cup dry. A loaf makes ~6 cups fresh breadcrumbs.
Estimating Without a Scale
Packaged bread lists net weight on the bag. For artisan: one-handed loaf = 9-12 oz (baguette). Two-handed = 1-1.5 lbs (standard). Heavy round = 1.5-2 lbs (boule). Slice as thick as your finger = ~1 oz (25-30g). Slice as thick as your thumb = ~1.6 oz (40-50g).
