What is Recipe Scaler Studio?
Recipe Scaler Studio is a free serving size calculator for home cooks. Enter or paste ingredients, set original servings and target servings, and see scaled amounts right away. It also helps with cooking measurement conversion (cups, tablespoons, grams, milliliters), shopping lists, and optional baker’s percentages.
Parsing is heuristic — common line formats work well, but unclear lines stay editable. Cook times and oven temperatures in steps are never auto-scaled. Everything runs in your browser; recipes are not uploaded to a server.
For calorie, macro, weekly meal planning, pantry, and grocery budgeting in the same Zero-Upload style, try Nutrition & Meal Planning Studio (/en/nutrition-meal-planning-studio/).
How to scale a recipe
Set original servings and target servings (or use presets like 0.5×, 2×). Paste one ingredient per line, load an example, or enter rows manually. Scaled amounts appear as Original → Scaled.
Edit any scaled amount if you prefer a practical round number; that row is marked as manually adjusted. Then build a shopping list from the scaled recipe.
How calculations work
Scalable amounts use a simple multiplier: target servings ÷ original servings. Lines marked “to taste,” “as needed,” or similar stay non-scalable.
Optional practical mode rounds awkward counts (for example eggs). Display can use decimals, fractions, or smart formatting. Steps and notes are shown as written — never multiplied for time or temperature.
Unit conversions
The tools panel converts volume and weight within the same dimension, and can approximate weight ↔ volume when an ingredient density is selected (labeled approximate).
Temperature conversion includes Celsius, Fahrenheit, and UK gas marks with a reference table. These converters are separate from serving scaling so oven settings are not silently changed.
US vs Metric vs Japanese cups
A US cup is not the same as a Japanese cooking cup (カップ). The converter keeps these systems distinct so recipes are not mixed by accident.
Tablespoons and teaspoons also differ by region; prefer the unit written on your recipe, then convert deliberately if needed.
Shopping lists
Build a checklist from scaled ingredients, add or edit items, clear completed lines, and copy the list. Merging is conservative — only matching names with compatible units combine automatically.
Privacy
Scaling, exports, and optional local saves use your browser. We do not claim absolute safety against every device threat, but your recipe text is not sent to Solasu servers for this tool.
Share links encode a compact recipe in the URL fragment on your device. Very large recipes may be too big for a link — use file export instead.
FAQ
What is a recipe scaler / serving size calculator?
It multiplies ingredient amounts by the ratio of target servings to original servings so you can cook for more or fewer people without rewriting the whole recipe by hand.
Does it automatically change cook times or oven temperature?
No. Steps, tips, and temperatures stay as you wrote them. Only ingredient amounts are scaled — adjust heat and timing yourself.
Will every pasted line be recognized perfectly?
No. The parser handles common formats (e.g. “200g flour”, “小麦粉 200g”) but is not AI-perfect recognition. Unrecognized lines remain editable.
Can I convert cups, tablespoons, grams, and milliliters?
Yes. Use the tools panel for same-dimension cooking measurement conversion. Weight ↔ volume needs a selected ingredient density and is approximate.
Is a US cup the same as a Japanese cup?
No. US cups and Japanese カップ differ. This tool treats them as separate units so they are not silently mixed.
Where are my recipes stored?
Optional saves use localStorage in this browser only. Your recipes stay in your browser for this tool and are not uploaded to a Solasu server.
Is it free?
Yes. No account is required to scale recipes or export lists.
Can I share a scaled recipe with a link?
You can copy a share URL that stores a compact recipe in the page hash. Large recipes may exceed the link size limit — export TXT, JSON, CSV, or HTML instead.
