Kids grow fast.
Our AI works faster.
Welcome to KidResize. We are revolutionizing parent-to-parent resale by building a platform that is a perfect mix between a shopping app and a social network. Combined with expert machine learning, we actively use your wishlist to surface similar items before they're gone and instantly match high-quality clothing to your child's exact size.

How Our Expert AI Works
We didn't just build a marketplace; we built a smart wardrobe assistant. Here is how our backend technology takes the guesswork out of sizing and shopping.
Predictive Fit Algorithm
Create a profile with your child's exact height, weight, and standard sizes. Our machine learning backend actively scans thousands of items to predict what will fit perfectly right now.
The "Fit-First" Feed
Flip the "Show Only Matching Sizes" switch on our homepage. In milliseconds, our engine filters out the noise, transforming the marketplace into a highly curated boutique specifically for your family.
Social Commerce & Smart Wishlists
KidResize is built like a mix between a shopping platform and social media. Follow your favorite parent sellers, and let our AI analyze your wishlist to hunt down similar trending items before they sell out.
Paid 3 Days After Delivery
While the AI handles the sizing, our financial infrastructure handles the trust. Payments are processed by Stripe. Seller payouts are released 3 days after delivery, so buyers have time to report an item that isn't as described.
Outgrew a whole size? Sell it as one lot.
Bulk lots bundle several pieces in the same size and gender, in Lightly used condition or better, into one listing with up to 20 photos. Shipping is priced by item count, or offer free local pickup.
Pardon our dust as we launch 🌱
We are actively working every single day to bring on new sellers, attract buyers, and train our systems. If you see a category waiting for its first item, it won't be empty for long.
