Sometimes price modifiers and additional images are not enough to differentiate your products. Product variations can help you assign different images for every product option in your store as well as to track the stock of options like sizes.
Check out a video about variations setup:
Understanding variations
Each possible set of options for a particular product is a variation for that product.
For example, a t-shirt that comes in two sizes (small and medium) and two colors (yellow and gray) has four variants:
Using variations
Variations help organize your store into separate nested products. With Product Variations feature, you can:
- upload separate images to each of the variants (frequently used for apparel and shoes)
- automatically adjust prices with customer selections
- track inventory with unique SKUs to prevent overselling
- adjust weight to get more precise shipping rates at checkout
Creating variations

F.A.Q. about variations
Here is a short list of answers to frequent questions along with some tips to use variations effectively in your store.
If I add a variation to a product, does that count as an additional product?
No. You can add as many product variations as you need, they don't count towards product limits. Ecwid counts products based on the number of products shown on the Products page in your Ecwid Control Panel.
Can I have different stock for each product size?
An item should have its own SKU and stock quantity so that its stock level can be automatically reduced upon sales. You can set a separate SKU and quantity in stock for every product variation in your store, i.e. for every combination of different options (usually it’s a combination of color and size).
Let’s say, you sell shoes and offer them in certain colors (Black, Red) and sizes (5, 5.5, 6, 6.5 7, or Large, Small, Medum, etc). You want to track inventory level of every variation of the product (e.g., Red 7) to know when it’s time to replenish its stock and make this variation unavailable for online purchase when its stock reaches zero. For this, first, add options Color and Size to that product and create Color + Size variations out of these options’ values, then assign a unique SKU and specify stock quantity for every product variation.

What if variation options differ between products?
There may be cases when you do not have consistent options across variations. For example, you have gray t-shirts in sizes XS, S, M and L and yellow t-shirts only in size S and M. You need to make sure your customers do not order yellow t-shirts in XS or L sizes.
For such situations we recommend that you create the variations for unavailable combinations of product options (for yellow t-shirts in XS and L in our example) and mark them as "Out of Stock":
Here is how it looks in your Control Panel:
Here is how it works when customers choose an out of stock variations in your store:
Is it possible to use the same SKU for the base product and its variations?
Yes, you can use the same SKU for a product and its variations if you don't need to track inventory for variations separately. However, Ecwid will prompt you to set a unique SKU once you change a variation stock, price, or weight. Once the variation is treated as a separate item, it should have its own SKU.
How to set the default variation?
A default product variation will show in the product details page based on the product's default set of options. For example, if "Gray" is the default option for "Color" and "Small" is the default for "Size", the variation "Gray, Small" will be this default variation. Your clients will see this when visiting your product details page for the first time:
If you do not need any preselected defaults, just tick the setting Do not preselect default value for product options in the Options tab where you edit product details:
Can I assign unique UPC/EAN codes to product sizes?
Yes, you can assign unique UPC values to product variations, like colors and sizes:
1. Go to Ecwid control panel → Catalog → Products page;
2. Create or select a product with variations;
3. Go to Options, then Variations tab in the product editing page;
4. Click on Manage link under the Stock column;
5. Add the UPC value for this variation in the UPC field: 
6. Save the changes.
UPC of product variations can be scanned with the help of Ecwid mobile app (for Android)
Is it possible to use bulk discounts for variations?
Yes, you can offer tiered pricing for each variation based on quantity tiers. You can find the detailed instruction here: Bulk discount pricing.
How to manage variations in bulk
You can update the stock of existing product variations in bulk by using the built-in import tool in your store.
