How to maintain consistent font size in product descriptions?

Store Design

Topic summary

A user is experiencing font size inconsistencies in product descriptions after editing or pasting content. The edited text appears smaller than the rest of the description on the live site.

Likely Cause:
Copying and pasting content carries over hidden formatting from the source, which conflicts with the store’s default styling.

Suggested Solutions:

  • Paste text into a plain text editor (like Notepad) first to strip formatting, then copy again into Shopify
  • Use Shopify’s HTML editor: click the <> button before pasting, then click <> again after (note: this may break paragraph formatting)
  • On Mac: use TextEdit in plain text mode (Format > Make Plain Text) before pasting

The issue remains unresolved pending the user’s attempt at these workarounds.

Good Day,

When I go to edit a product description and add or copy and past details into the description box. After saving and looking at the save version on my site, the edited text font has reduced in size. How do I fix it where my edited details are consistent with the rest of the font?

Hard to be specific without seeing your storefront, but one possible cause is that when you copy and paste some formatting will be inherited from your source.

There are ways to prevent this:

  • Paste your copied text to a plain text editor like Notepad first, then copy from Notepad and paste into Shopify (on Mac use TextEdit and do Format=> Make plain text before copying); or
  • When copying into Shopify, click </> button first, paste, then click </> again. This will break all the paragraphs, but will ensure there is no unwanted formatting.
