Our Technology

Our team members have a research background from some of the best universities in the world (Stanford, MIT, Cambridge, Brown, TU Munich). This knowledge, state-of-the-art research, and the latest breakthroughs in computer vision and deep learning enabled us to develop a unique and patented technology.

How does it work?

Front-end

Presize is a whitelabel solution, seamlesly integrated directly into your webshop. We insert a custom designed "find my size" button on your product detail page.

With just a few lines of code and zero IT capacity, Presize is easy to integrate in any shop system (through Google Tag Manager) and still GDPR compliant.

Questions

We ask users about their height, weight, age, and gender. This helps our algorithm to give users who decide not to record a video a size recommendation. If users record a video, the questionnaire data is used to initialise the 3D model generation to decrease the calculation time.

Video Scan/3D Model

The 3D models we produce in the background are our key to offering the most accurate solution on the market.

We are currently improving the aesthetics and plan to show them to users in 2021 unlocking unseen visualization options.

Body Measurements

We extract up to 30 body measurements  according to ISO standards. Everything from ankle to neck.

With our technology, we gain body data insights and learn how the end customer really looks.

Size Recommendations

Our algorithm is constantly learning from transactional data. Combining the knowledge about every body measurement with the knowledge of whether that user kept or returned a certain product in a certain size is extremely powerful. We get to a per-product level, even if we have no product data at all except a generic size chart.

Our detailed fitting info can tell you exactly how different garment sizes fit different parts of your body.

Data engineering

We combine and augment multimodal data from several sources and constantly acquire new labelled data every week to improve our algorithms.

Our initial product data requirements are very low. Generic size charts are sufficient to give accurate size recommendations, while past returns from similarly shaped users help us improve future size recommendations. Any additional data further improves our results.

Hyper personalization

The Size-ID is the key for the end-user’s perfect fit. It is anonymous, shareable, and does not require user registration – we simply store the data up to 90 days within cookies. Alternatively, the user can register to keep their ID forever. Your recurring customer base will continue to expand as users are guaranteed the perfect fit every time. Understandably they get frustrated when they go to select their size for a product they like, only to find it unavailable. With Presize, you can choose to display only the products where the shopper’s size is available and shoppers can even order products for their body shape. We open you to unprecedented, hyper-focused retargeting options based on user bodies.

How far we’ve come

When we built our first prototype in 2018, we had to wait an hour for a result and it was off by more than 8 cm on average. That changed completely thanks to years of trial and error, massive data collection efforts, research breakthroughs, continuous effort of some of the best people in the computer vision domain in the world, and (honestly) a tiny bit of luck. Today we are at 1.2 cm MAE across all measurements and are carving off a few millimetres per month with continuous RnD.

Step 1

Requirements gathering questionnaire

A meeting with one of our product experts where we will ask questions to identify all the necessary requirements and solutions to get the best out of Presize for your online shop. This service is optional and can be requested.

Step 2

Specific product data integration requirements

Presize uses three types of data to produce a size recommendation: Product data, Sizing data, and Transactional data.

We can work with any lists of products like Excel files, JSON files, CSV files, but what we must have is a sizing chart for at least one product in the shop.

We also give our customers the option to integrate with the bare minimum of information that we need to recommend sizes for products, but encourage you to provide us more information so we can provide the most value to you and your customers.

Data Type

Minimum integration data

Ideal integration data

Product data

List of available products

Excel files, JSON files, CSV files that contain ID, Name, URL, Gender, Category and the available Sizes for each product. If your shop uses sizing data for different fits, please also include the Fit.

Daily updated feed as CSV/JSON via URL

CSV: Provide a feed as CSV via URL that contains the product’s ID, Name, Gender, Category, Brand, Collection, Price, Fit, URL, Image, Sizes, Measurements, Material and Stretch. Again, if using per-sizing. JSON: Export the products as a list of JSON files with the ID, Name, Gender, Category, Brand, Collection, Price, Fit, URL, Image, Sizes, Measurements, Material and Stretch.

Sizing data

Sizing charts in any form

Excel files, JSON files, CSV files that contain ID, Name, URL, Gender, Category and the available Sizes for each product. If your shop uses sizing data for different fits, please also include the Fit.

We like to take machine readable data (Excel files, JSON files, CSV files) over images, but for a limited number of charts even images are okay.

Sizing charts as CSV containing all available sizing data

Provide us the sizing charts as CSV files in the following format, named after either the product, brand or category of the associated products.

Transactional data

Exports of order and return data

We encourage you to provide transactional data that we can use to improve the recommendations over time. Any machine-readable file that contains the information about Order, Product, Size and Status is sufficient.

Daily updated transaction data feed as CSV/JSON via URL

Provide a transaction data feed as CSV via URL containing the Date, Order, Product, Size, Status, Reason, and Comment fields and notify us or agree upon intervals in which the feed is updated on your end.

Step 3

Simple GTM integration

For the quickest and most efficient integration of our solution we are using Google Tag Manager (GTM) on your website. GTM is used by the vast majority of fashion eCommerce shops. It allows us to integrate within a day without the involvement of your IT department.

You have the possibility to invite Presize's GTM account to your GTM project and then we take care of the tasks like testing, integrating, and releasing (if you want to give us publish rights).

A direct integration on your website by pasting a JavaScript snippet provided by Presize is also possible.

We track the entire funnel, from the number of times the Presize solution was shown to shoppers on a product page, all the way up to orders and even returns.

Step 4

Integration on staging environment

After the integration passed our internal QA tests, you can also test everything before it is moved to production.

Step 5

Go Live!

Congratulations! From now on, you will have more conversions, fewer returns, and higher customer satisfaction.

Your Virtual Tailor for MTM, Workwear, Fitness & More

With our rapid integration it takes only 30 minutes to set up our body scanning software all by yourself.

You will get a URL and a QR Code that will lead your users to the scanning application. You can put this on your web page, for example. Then you can log in to your dashboard and see the body measurements of all your customers that have been measured. An email address or a Size-ID can be used to associate scans with orders and customers.

You can read our body measurement solution case studies to see example use cases. For insights on our rapid integration, download and view the Presize integration document.
