FAQ
Questions people ask
Quick answers for the most common bold‑text questions.
How long should a bold line be?
3–8 words is a good range. Short lines feel cleaner and more readable.
Should I bold the entire paragraph?
No—bold only the key phrase or heading to keep content readable.
Will bold text work on mobile?
Unicode bold works on most modern devices, but always preview first.
Why does the bold text look uneven?
Different system fonts render Unicode glyphs differently. Shorter lines help.
