Product Dimensions 1 is the first of two free-text dimension fields on a Macy's listing. Macy's asks for it as Length x Width x Height in inches or feet, capped at 254 characters including spaces, and it is optional. A filled value appears on the product detail page.
The value is set per variant and shared across variants that use the same product images, which for most styles means one entry per colorway. For a dimension that changes by size, use Product Dimensions 2, which is shared by size.
Rules
| Rule | Requirement |
|---|---|
| Required | No |
| Format | Length x Width x Height |
| Units | Inches or feet, stated in the value |
| Length | Up to 254 characters including spaces |
| Content | Plain text; no HTML |
Osello's recommendation is to write the unit once, use a lowercase "x" between the numbers and keep decimals to a quarter inch: 13.25" L x 5" W x 8.5" H.
Examples
| Value | Verdict | Reason |
|---|---|---|
| "13.25" L x 5" W x 8.5" H" | Good | Macy's order, one unit, plain text |
| "18 x 12 x 6 in." | Good | Order followed, unit stated |
| "13.25 x 8.5" | Weak | Two numbers and no unit; the shopper cannot tell which is which |
| "Approx. 34 cm long" | Weak | Metric only and not the L x W x H format |
| "Fits a 15" laptop" | Weak | That is a Highlights bullet, not a dimension |
Common mistakes
- A different order than Length x Width x Height.
- Dropping the unit, or inches on one product and centimeters on the next.
- Weight, capacity or care text in the field.
How Osello fills this field
Osello treats Product Dimensions 1 as an optional, variant-level text field shared by every variant that uses the same product images. The AI fills it from the source attributes or measurements when the data states them, and leaves it blank rather than estimating when it does not. Values are limited to 254 characters and HTML is stripped. Measurements stored on a Shopify product can be mapped through Shopify metafields.
Frequently asked questions
Is Product Dimensions 1 required on Macy's?
No. Leaving it blank does not block a submission. Fill it when the item's size matters to the purchase, such as bags and accessories.
Which unit should I use?
Inches or feet, per Macy's definition of the field. State the unit in the value so the shopper knows which you used.
Should I use Product Dimensions 1 or 2?
Use 1 for the dimensions that hold for a whole colorway. Use 2 for a dimension that changes with size, since Osello shares that field by size instead of by image set.
