Product Title Builder

Assemble a title from feed attributes and see where it exceeds the character limit or gets cut off in the visible area. Everything you enter stays in your browser.

▸How to use
  1. Add elements.Pick the feed attributes that make up the title, or a static value. Static values don't exist in your feed — they're text you type directly into the attribute rule.
  2. Enter values.The closer these are to what's actually in your feed, the more accurate the character count will be.
  3. Reorder.Drag, or use ↑↓. Unchecking an element removes it from the result without deleting it.
  4. Check where it gets cut.Move the visible-width slider — anything beyond it turns grey. The listing preview below updates with it.
  5. Read the spec check.It flags length overruns, formatting mistakes, and wording that may be treated as promotional text.
  6. Copy.Take the assembled title straight out.

This tool is not about what words to write. It's about which attributes to use, in what order, and how far to go. Once the attributes are in order, the same design can be applied to every product through an attribute rule.
Everything you enter is processed in your browser only. Nothing is sent or stored anywhere. Reloading the page clears it.

Static values (typed directly into the attribute rule)

※ Names in [ ] are feed attribute names; the number after them is the limit stated in the Help Center. All counts are in half-width units (full-width = 2, half-width = 1).
※ Attributes with a fixed set of accepted values (condition, gender, age_group, is_bundle, etc.) are not listed, because concatenating them outputs the raw English value.

※ Counts use half-width units: a full-width character counts as 2, a half-width character as 1.
※ The Help Center notes that roughly the first 70 characters are typically shown. Actual visibility varies by screen size.

Spec check
  • Looks like capitalization for emphasis: ABC (acronyms, country and currency codes are fine)
  • Material [material]: Only one value is accepted. For multiple materials, give one primary plus up to two secondary, slash-separated (e.g. cotton/polyester/elastane).
  • Color [color]: Multiple colors are slash-separated (e.g. red/pink/blue), up to 40 per individual color.
  • Size [size]: Use slashes, not commas, for multiple sizes or dimensions (e.g. 16/34). Don't put multipack quantity in size.
