# Amount Types Reference

[Order Minimum/Maximum Amount Limits for WooCommerce](https://wpfactory.com/item/order-minimum-maximum-amount-for-woocommerce/) can limit an order by eleven different measures, called amount types. This reference lists each one, the internal id used in option and meta names, its unit, and how Order Min/Max Amount measures it from the cart.

| Amount type | Type id | Unit | How it is measured |
| --- | --- | --- | --- |
| Sum | `sum` | Store currency | Cart total or subtotal, adjusted by the "Sum" amount type options. |
| Quantity | `qty` | pcs | Total number of items in the cart. |
| Weight | `weight` | Store weight unit | Sum of product weight times quantity. |
| Volume | `volume` | Dimension unit cubed | Length x width x height x quantity (non-virtual products). |
| Length | `length` | Dimension unit | Sum of product length times quantity. |
| Width | `width` | Dimension unit | Sum of product width times quantity. |
| Height | `height` | Dimension unit | Sum of product height times quantity. |
| Area | `area` | Dimension unit squared | Length x width x quantity (non-virtual products). |
| Products | `product` | count | Number of different products in the cart. |
| Product categories | `product_cat` | count | Number of different product categories in the cart. |
| Product tags | `product_tag` | count | Number of different product tags in the cart. |

### Notes

- Weight, volume, and dimension types read the values on each product's **Product data > Shipping** fields. Products with no dimensions contribute nothing to those totals, and virtual products are skipped for volume, length, width, height, and area.
- Global limits are stored as `alg_wc_oma_{min|max}_{type}`; per-product and per-user limits use the meta key `_alg_wc_oma_{min|max}_{type}`.
- You can restrict the `product_cat` and `product_tag` counts to specific terms with the "Terms to include" and "Terms to exclude" options on the General tab.
