What platform are you using for your website @pipersplaygroun?

When on the add a product page, click on Inventory and Options and you can add your sizes there.
You would create an option name called Size and then add the sizes and price differences there. You could do the same for color options as well.
Is that what you were looking for?
Thank you @Muse but I was looking for a drop down box like they have for how to arrange the items (newest, a-z, etc). I know how to do it in the inventory but I don't carry multiple sizes of the same items. My customers have a hard time finding their size. I am just looking for something easier other than having to type their size in the search bar. Is there a way to arrange categories by size? If you know of an easier way please let me know. Thanks for the response.
My response was to the original poster.
The ability to search by size is not available -- that I am aware of.
The only workaround I can think of is creating product name categories. Then, create subcategories by size.
Folks can then navigate to the category they want and choose the size subcategory and see all the sizes you offer for that category -- or not -- and gravitate to their size.
