Frequently Asked Questions (FAQs)
Is this estimate 100% accurate?
No, this is a simplified estimation for quick reference. The actual file size depends on the number of weights, styles, and character subsets you choose to include. The tool's goal is to provide a general performance awareness.
How can I drastically reduce font file size?
The single most effective method is subsetting. If you only need characters for English, load only the 'latin' subset instead of the entire font. The Google Fonts CSS Generator tool can help with this.
