أنشئ مقياس طباعة نموذجيًا من أي حجم أساسي ونسبة (من 1.125 إلى 1.618) وانسخه كخصائص CSS مخصصة أو إعدادات Tailwind.
| الخطوة | px | rem | em | ارتفاع السطر | المعاينة |

يضرب المقياس المعياري الحجم الأساسي بالنسبة عند كل خطوة صعودًا، ويقسم عليها عند كل خطوة نزولاً. الخطوة 0 هي الأساس، الخطوة 1 = الأساس × النسبة، الخطوة −1 = الأساس ÷ النسبة، وهكذا.
يقل ارتفاع السطر المقترح كلما زاد الحجم: 1.6 للنص الأساسي، 1.4 للعناوين، 1.1 لأحجام العرض — ويُحسب كـ `1.7 − 0.1 × عدد الخطوات فوق الأساس` مع تقييده بين [1.05, 1.7].
A modular scale multiplies one base size by a fixed ratio for each step up and divides for each step down. This generator produces ten steps, from −5 to +4, using size = base × ratio^step, so at the default 16 px base and 1.2 ratio, step +1 is 19.20 px and step −1 is 13.33 px. Each row also reports rem (px ÷ 16), em (px ÷ base), and a suggested line-height of 1.7 − 0.1 × (step + 5), clamped between 1.05 and 1.7.
The ratio dropdown is the real design decision. Minor second 1.067 and Major second 1.125 give tight, dense scales suited to dashboards and data-heavy interfaces. Minor third 1.2, the default, and Major third 1.25 suit most websites. Perfect fourth 1.333, Augmented fourth 1.414, Perfect fifth 1.5 and Golden ratio 1.618 open up fast and work best for editorial or landing pages. Base size accepts 8 to 32 px, and the CSS variable prefix defaults to --fs.
Two caveats are worth knowing before you paste the export. The rem column always divides by 16, so if you change the root font size in your own stylesheet the exported rem values will no longer match the pixel figures shown. And the step names are offset from the arithmetic: the ten tokens run xs, sm, base, md, lg, xl, 2xl, 3xl, 4xl and 5xl across steps −5 to +4, which places step 0 — the size you actually typed — under the name xl rather than base.
1.2, the minor third, is the default and the safest for general web work. Go tighter with 1.125 for information-dense interfaces where many sizes must coexist. Reach for 1.5 or the 1.618 golden ratio only when you have few sizes and want dramatic headline contrast.
Yes. The Copy Tailwind fontSize block button puts a ready-made fontSize object on your clipboard, each entry pairing a rem value with its calculated lineHeight. The Copy CSS custom properties button instead emits a :root block using whatever variable prefix you have set.
It falls as size grows, using 1.7 − 0.1 × (step + 5) clamped into a 1.05 to 1.7 range. The smallest step receives 1.7 and the largest steps bottom out at 1.05. Treat it as a starting point and adjust once you know your real line length.
rem always divides the pixel size by 16, the browser default root size, while em divides by whichever base you entered. With a 16 px base the two columns are identical; set the base to 18 and they diverge at every step of the scale.
You cannot from this tool, which always outputs the same fixed ten steps from −5 to +4. To extend the range, multiply the largest value by the ratio again yourself, or lower the base size and shift which portion of the scale you use.
