Manage Size Chart

The size chart allows buyers to have a better experience when choosing their product, thus avoiding size changes and/or claims; so consider using this functionality on your fashion listings.
There are two possible types of size chart: brand or specific type (created by the seller).


Experience goals

  • Ensure that fashion publications are always created with a size chart.
  • Ensure that products are published with the right size chart.
  • Seek to make this task as easy as possible so that we do not have dropouts by users when choosing or creating a size chart.


Create size charts in footwear

Remember the technical sheet received when you upload the attribute required for the template, since this technical sheet will have the attributes that you must send in the size chart creation POST. If you send an attribute that is not on the technical sheet, it will return an error.




Some considerations about attributes:

  • names: The name that identifies the Size Chart must be unique.

The name should be replicated for the site_ids where the Size Guide will be created, there is no need to translate it. The name should be easy to reference, for example: "Girls' Shoe Size Guide", "Men's Oxford Size Guide".



    {
    "names": {
    "CBT": "SIZE CHART FOR CBT-MAN US-M ",
    "MLM": "SIZE CHART FOR CBT-MAN US-M ",
    "MLB": "SIZE CHART FOR CBT-MAN US-M ",
    "MCO": "SIZE CHART FOR CBT-MAN US-M ",
    "MLC": "SIZE CHART FOR CBT-MAN US-M "
    },
  • domain_id: define this with available domains for size chart documentation.
  • site_id: always is CBT.
  • type: can be SPECIFIC or BRAND.
  • main_attributes: it is filled according to the rule that the size chart has and will represent the main size that will be displayed in the publication (column that will be the main size).

You can recognize the available main attributes with tag main_attribute_candidate when you're consulting a size charts data sheet.


These are the rules for main attribute:



Note:
This chart is an example, in order to have the accurate Main Attribute to domains please check technical specs.

You have to send one for any name of the size chart (an array structure with site_id and id of the main_atttributes). The main_attribute must be the same for all site_ids where the Size Guide will be used.


  • secondary_attributes: it's optional and represents other standard, local or manufacturer sizes. Although the secondary attribute is optional, if used, it must adhere to the following structure.


  • Attributes: please send all attributes recognized consulting domain data sheet with the required tag, for example GENDER, COLOR, FOOT_LENGTH. In addition, you can send all optional attributes identified with grid_filter tag, for example BRAND.
  • Gender: is one of mandatory attributes and remember that chart gender must match to item gender. The available ID are:
    • Woman ID 339665
    • Man ID 339666
    • Girls ID 339668
    • Boys ID 339667
    • Gender neutral ID 110461
    • Gender neutral KID ID 1915949

  • FOOT_LENGTH and FOOT_LENGTH_TO: are range attributes used to create measurement ranges within the specification of a size chart row.
  • Rows: contains sizes related to the size chart.
  • Size: determine the picker information (descriptive detail of the size). First column can be set by the seller to change what we want to show as the size description. SIZE value must match with the SIZE CHART ROW in the main_attribute. The first column of the size chart will always be identified under the id of the SIZE attribute.

Create charts in TOPS and BOTTOMS domains

Important:
Now it is available to associate a size chart to an item at TOPS and BOTTOMS categories.
The size charts of the TOPS and BOTTOMS domains, will be able to work with list type attributes allowing multiple values (multivalued), for example: for an attribute id: SIZE with name: S - L we will allow to load multiple values in the attribute id: FILTRABLE_SIZE with name: S,M, L
For TOPS and BOTTOMS categories, it will only be possible to create publications from custom size charts (SPECIFIC). Please check the section Available domains for size chart.
Starting from February 2024, size guides can be created, specifying attributes of garment measurements, such as garment length, garment width, inseam, among others, according to the needs of each seller.

For TOPS and BOTTOMS domains, such as: pants, shirts, dresses, among others. Should consult of the list available domains for size chart We included attributes of the data type value_type: list a List, which contains a set of international values predetermined by Mercado Libre to specify certain attributes of a customized size charts, additionally you will find the multivalued tag that will allow you to create the charts with one or more specific values within the list for each row, for example tops: you can see that the size XLarge includes the values of the size list from 3XL TO 6XL (3XL,4XL, 5XL.6XL) while the size Small corresponds to a value of size XS and S. Also for bottoms use american size, example: 0 US, 16 US, 24 US



In the TOPS and BOTTOMS domains only SPECIFIC charts can be used, or customized charts specified by each vendor. When consulting the technical data sheet of the size charts you will see in the result a list data type that determines a List, this attribute will indicate the possible values that it can take, both its value_id and its value_name. It is mandatory for the values of filtrable sizes to exist in the technical spec.

Create charts with clothes sizes

Important:
From February 2024 for TOPS and BOTTOMS domains only, it will be possible to create size charts allowing the seller to specify clothes sizes. For testing, we have enabled the PANTS_TEST domain on all sites for the "Woman" gender only with the new configuration.

Only for TOPS and BOTTOMS domains, after consulting the size chart data sheet and recognizing which attributes have the CLOTHING_MEASURE tag, you will be able to create size charts only by specifying clothes sizes.


To consider:

  • The "measure_type" field must be specified and its possible values: BODY_MEASURE or CLOTHING_MEASURE. This field refers to the type of measure that the seller will specify in the size chart. Once the size chart has been created, this field cannot be modified.
  • The same size chart cannot have both garment and body measurements at the same time.
  • If the "measure_type" field is not sent by default, the size chart will be of body measurements or BODY_MEASURE and all Validations will be based on this type of measurement.

Example of the creation of a customized size chart, with clothes sizes:

Update Rows - Size chart

This endpoint allows you to add information to an existing row in the size chart. It's impossible to modify the information of the rows. You can not edit the main item (main_attribute) of each queue (row) and neither can you delete queues.
It is possible to add information to a line that was not filled in.

Size chart



Modify size charts

From a previously created size charts it will only be possible to modify the name field. If a mistake was made when creating the size charts, e.g. in the main sizes or in the gender assignment, the size charts must be recreated.


Important:
Note that when modifying, you will not be able to edit the main size (main_attribute) of the charts, such as the value of the main size of the (row) and the general attributes. Size charts may not be removed.

Request:

curl -X PUT -H 'Authorization: Bearer $ACCESS_TOKEN' -d{...}https://api.mercadolibre.com/catalog/charts/$CHART_ID

Example:

curl -X PUT -H 'Authorization: Bearer $ACCESS_TOKEN' -d
'{
    "names": {
        "MLC": "New name MLC",
        "MLM": "New name MLM",
        "MLB": "New name MLB",
        "CBT": "New name CBT",
        "MCO": "New name MCO"
    }
}'

International Size Convert

Important:
New Feature: The size chart equivalence to local sizes is now done automatically by Mercado Libre.

In order to facilitate the creation of the size guide, it is now required to include only international sizes in the size chart. Consequently, the inclusion of local sizes (Brazil, Mexico, Colombia, and Chile) will be fully automated by our functionality, thus simplifying the size chart creation process for sellers.
In the image below, there is an example of how it will look. The "International Size" column pertains to the sizes added by the seller. The other columns with the names Brazil, Mexico, Colombia, and Chile have the equivalences added automatically by our functionality.
Automatic equivalence is available for both tops & bottoms size charts and for footwear.


Tops & Bottoms





Footwear



Important:
We recommend not adding photos, tables, or equivalence texts in the item description, as the generation of these equivalences for countries will now be done automatically.

Search for equivalence size

To view international sizes, you can perform a GET request to list the equivalences. This valuable information allows you to know the local sizes of each country (Brazil, Mexico, Colombia and Chile) compared to the international size.
The request requires three query params: domain, gender and siteId.


  • Woman
  • Man
  • Gender neutral
  • Girls
  • Boys
  • Gender neutral kid
  • Babies
  • The available site_Id are:
  • MLB
  • MLM
  • MCO
  • MLC
Note:
Remember, gender and domain are mandatory information and siteId is optional information.

Request:

curl -X GET -H 'Authorization: Bearer $ACCESS_TOKEN' https://api.mercadolibre.com/marketplace/sizechart/equivalences?siteId=$SITE_ID&domain_id=$DOMAIN&gender=$GENDER

Example:

curl -X GET -H 'Authorization: Bearer $ACCESS_TOKEN' https://api.mercadolibre.com/marketplace/sizechart/equivalences?domain_id=T_SHIRTS&gender=Gender neutral kid

Response: Success 200 OK
