Hi @Mikeslie 
Sorry, I’m not sure whether you’ve already managed to fix the issue with enlarging the text inside the Dawn theme dropdown, but if you’re still looking for an easy, quick, and code-free solution, I’d like to introduce you to a highly effective solution — the Easify Product Options app.
Instead of editing your theme’s CSS (which can be complicated and easily overwritten whenever the theme updates), you can simply replace Shopify’s default dropdown with Easify’s customizable dropdown. All font sizes, font styles, colors, and more can be adjusted directly from the app’s Settings interface — no coding required.
Here’s an example I’ve created so you can see how it works:
You can create a complete Option Set and customize the font size directly inside the app’s Settings. Just go to Easify Options → Settings → App Design → Font, and you’ll find all the typography controls you need — including font size for labels, dropdown text, selected values, as well as additional settings like font family, text color, spacing, padding, border radius, and more. You can increase the text size to whatever you prefer — for example 16px, 18px, 20px — and the product page will instantly reflect those changes.
What’s great is that you’re not limited to customizing dropdown text. You can also style checkboxes, radio buttons, buttons, file uploads, and other option types — all within the same design panel, as shown in the screenshot. This allows you to create a much cleaner and more visually appealing options section compared to the default Dawn theme, fully aligned with your brand’s style.
You’ll find this app both easy to navigate and powerful for managing custom options. And whenever you need help, Easify’s support staff is quick and friendly.
