## Abstract

In various example embodiments, systems and methods to provide content recommendations are provided. Search parameters are received from a user. An attribute associated with the user is derived. Using the search parameters and the attribute, content from a database that is within a predetermined margin of difference of the derived attribute are determined. A list of the content is caused to be presented in a user interface of the user.

## Claims

### Claim 1

A method comprising:
receiving a search parameter from a device of a user;
receiving an image showing the user and a marker;
identifying the marker in the image and determining dimensions of the marker from a marker database storing the dimensions of the marker;
deriving sizing data for the user using the dimensions of the marker and the image showing the user and the marker;
performing a search of a coupled database for content corresponding to the search parameter and having a size within a predetermined margin of difference of the derived sizing data for the user; and
causing presentation of a list of the content in a user interface of the device of the user.

### Claim 2 (depends on 1)

The method of claim 1, wherein the receiving the search parameter comprises receiving a selection of a category.

### Claim 3 (depends on 1)

The method of claim 1, further comprising:
generating the list of the content; and
prioritizing the content on the list based on past interactions performed by the user.

### Claim 4 (depends on 3)

The method of claim 3, wherein the past interactions comprises a browsing history of the user or a purchase history of the user.

### Claim 5 (depends on 1)

The method of claim 1, further comprising:
generating the list of the content; and
prioritizing the content on the list based on past interactions performed by related users.

### Claim 6 (depends on 5)

The method of claim 5, wherein the related users are other users having a pre-existing relationship with the user, the pre-existing relationship being stored in a user profile of the user.

### Claim 7 (depends on 5)

The method of claim 5, wherein the related users are other users having the same derived sizing data as the user.

### Claim 8 (depends on 1)

The method of claim 1, wherein the margin of difference is a preference set by the user.

### Claim 9 (depends on 1)

The method of claim 1, wherein the derived sizing data is derived by also using information from a user profile of the user.

### Claim 10

A system comprising:
one or more hardware processors; and
a memory storing instructions that, when executed by the one or more hardware processors, cause the one or more hardware processors to perform operations comprising:
receiving a search parameter from a device of a user;
receiving an image showing the user and a marker;
identifying the marker in the image and determining dimensions of the marker from a marker database storing the dimensions of the marker;
deriving sizing data for the user using the dimensions of the marker and the image showing the user and the marker;
performing a search of a coupled database for content corresponding to the search parameter and having a size within a predetermined margin of difference of the derived sizing data for the user; and
causing presentation of a list of the content in a user interface of the device of the user.

### Claim 11 (depends on 10)

The system of claim 10, wherein the operations further comprise:
generating the list of the content; and
prioritizing the content on the list based on past interactions performed by the user.

### Claim 12 (depends on 11)

The system of claim 11, wherein the past interactions comprises a browsing history of the user or a purchase history of the user.

### Claim 13 (depends on 10)

The system of claim 10, wherein the operations further comprise:
generating the list of the content; and
prioritizing the content on the list based on past interactions performed by related users.

### Claim 14 (depends on 13)

The system of claim 13, wherein the related users are other users having a pre-existing relationship with the user or other users having the same derived sizing data as the user.

### Claim 15 (depends on 10)

The system of claim 10, wherein the derived sizing data is derived by also using information from a user profile of the user.

### Claim 16

A hardware storage device storing instructions which, when executed by at least one processor of a machine, cause the machine to perform operations comprising:
receiving a search parameter from a device of a user;
receiving an image showing the user and a marker;
identifying the marker in the image and determining dimensions of the marker from a marker database storing the dimensions of the marker;
deriving sizing data for the user using the dimensions of the marker and the image showing the user and the marker;
performing a search of a coupled database for content corresponding to the search parameter and having a size within a predetermined margin of difference of the derived sizing data for the user; and
causing presentation of a list of the content in a user interface of the device of the user.
