How can I change the default paragraph font size in my product description?

Topic summary

  • Issue: The product description text appears too large by default; the requester wants to reduce the paragraph (body) font size in a Shopify theme.

  • Solution provided: Edit code > Layout > theme.liquid. Locate the body CSS block (around lines 176–194) and change font-size: 1.5rem and, within the @media (min-width: 750px) rule, font-size: 1.6rem to smaller values (suggested 1.2rem). Save and check the product page.

  • Technical note: rem is a CSS unit relative to the root font size; the media query sets a different size on wider screens (≥750px), so adjust both values for consistent sizing.

  • Outcome: The original poster confirms the change worked. Another participant also expressed thanks. The thread is effectively resolved, with a screenshot provided to illustrate where to edit the code.

Hello! I’m trying to change the default paragraph font size and make it smaller as I find the product description to be somewhat large (especially with the font I decided to use)

Any help will be appreciated!

Hi,

To change the body font size (default paragraph font size), please follow the steps below.

  1. Go to Edit code > Layout > theme.liquid file

  2. Find the code below. (line 176-194)

body {
        display: grid;
        grid-template-rows: auto auto 1fr auto;
        grid-template-columns: 100%;
        min-height: 100%;
        margin: 0;
        font-size: 1.5rem;
        letter-spacing: 0.06rem;
        line-height: calc(1 + 0.8 / var(--font-body-scale));
        font-family: var(--font-body-family);
        font-style: var(--font-body-style);
        font-weight: var(--font-body-weight);
      }

      @media screen and (min-width: 750px) {
        body {
          font-size: 1.6rem;
        }
      }

  1. Edit font-size: 1.5rem and font-size: 1.6rem to fit your needs (recommend 1.2rem).

  2. Save the file and check the product page for the description text size.

Hope it helps.

Thanks.
