Per-Variant Limits

Limit Specific Variants

Sometimes the constraint is not on the product as a whole but on a particular variant. OrderRules lets you set limits at the variant level so you can restrict popular sizes or options without affecting the rest.

How to Set Variant Limits

1. Go to Product Limits
2. Click Add Product Limit
3. Select the product
4. Choose the specific variant you want to limit (for example, "Size Large")
5. Set your min and/or max quantities
6. Click Save

Example: T-Shirt Size Limits

Product:   T-Shirt
Variant:   Size Large
Max:       5 per order

Other sizes: No limit

Result:
  Customer orders 5 Large shirts:  OK
  Customer orders 6 Large shirts:  Blocked
  Customer orders 10 Small shirts: OK (no limit on Small)

Example: Limited Color Run

Product:   Handmade Mug
Variant:   Color: Gold Edition
Max:       1 per customer (lifetime)

Result:
  First order: Customer buys 1 Gold mug -- OK
  Second order: Customer tries Gold mug again -- blocked
  Customer buys Blue mug: OK (no limit on Blue)

When to Use Variant Limits

• Popular sizes that sell out fast and you want to distribute fairly
• Limited colorways or special editions within a product line
• Different production capacity per variant (for example, custom engraving only available in small batches)
• Premium variants that are more labor-intensive to produce

How It Works at Checkout

If a customer exceeds a variant-level limit, checkout displays a specific error:

"You can only order 5 units of T-Shirt (Size Large) per order."

The error names the exact variant so customers know which item to adjust.

Combining with Product-Level Limits

You can set both product-level and variant-level limits. Both are enforced:

• Product limit: Max 10 T-Shirts per order (any variant)
• Variant limit: Max 5 Large T-Shirts per order

A customer ordering 6 Large and 5 Small would be blocked by the variant limit on Large, even though the product total (11) also exceeds the product limit.
