How can I add the same font to all my titles, subtitle and paragraphs?

Topic summary

Request to make font consistent (Montserrat) across headings, subheadings, and paragraph text on a Shopify site. The author sees headings rendering differently than text blocks and says heading formatting can’t be changed, while text boxes allow size selection. Screenshots are attached to illustrate the mismatch.

Responses emphasize that headings are typically styled differently (size/capitalization) by default and ask whether there’s a CSS issue. The suggestion is to use CSS (Cascading Style Sheets) to explicitly style headings and text consistently.

Action items requested: provide an inspectable URL and more detailed context (theme, code, specific pages) to diagnose whether theme typography or custom CSS is causing the difference. Links were provided on how to ask better questions and supply reproducible details.

Status: unresolved. Next steps are to share a live example and, if desired, override theme styles via CSS so h1–h6, subtitles, and paragraphs all use Montserrat with desired sizes.

Hello everyone,

I am having troubles understanding how the heading, subheading and paragraphs fonts work…For instance, here is this screen shot I have the title in a different font than the subtitle. I used Montserrat Font for the entire website but for some reason the wrriting looks different sometimes.

Please see attached the screenshot.

Many thanks.

@Lumify Do you have broken CSS is that what the question is?

Otherwise you need more effort to be drastically more descriptive, or also provide better supplementary visuals.

All you’ve done is highlight two areas that are expected to be different font sizes and different capitalization.

It’s next to impossible to tell what your referring to unless someone is intimately familiar with a specific theme, specific fonts, your specific code, etc etc

Hi PaulNewton,

Thanks for taking the time to respond.

Its simple, I would like to have the same font on all heading titles (font montserrat) as the text description box.

When I add titles in heading it look different than the rest of the text and it’s imposible to change the format. When I use text boxes for description, I can choose the size of the text no problem. See screenshot.

"I add titles in heading it look different than the rest of the text "

Heading are literally supposed to be different sizes than the rest of the text.

" it’s imposible to change the format"

It’s not impossible, use css to style things for custom needs.

“I can choose the size of the text no problem.”

AND then what happens?

Provide some sort of inspectable url that shows the problem, and optionally a url that shows how you think it should supposedly work.

Good Luck.
