Enter the number of pieces and the type of audience. SizePlan calculates how many sizes to buy — no waste, no leftovers.
You don't know who will wear the garments. You only know the context. That's exactly why SizePlan exists.
Charity walk, fundraising dinner, sports tournament. You sell t-shirts to fund the project. You don't know who will buy, you don't know the sizes. SizePlan calculates the optimal distribution for a general audience or the specific profile of your participants.
Your band plays Friday night. You want to bring fifty hoodies to sell at the booth. Your audience has a fairly defined profile but you have no way to know what to order. SizePlan uses your audience's demographic profile to give you a reliable estimate.
You launch a limited edition collection. Your followers will order, but you don't know who they are physically — you only know they follow you. SizePlan uses the statistical profile of your audience type to give you a starting estimate to build your initial stock, without running out of M and being left with twenty unsold XXXL.
You bring fifty pieces to a craft fair, a vintage market, a weekend pop-up. You don't know who will come by — you only know what kind of event it is and what kind of audience it attracts. SizePlan translates that context into a concrete distribution, so you load the van with the right sizes.
No registration, no form to fill in. Just the information that matters. Result in less than a minute, editable and downloadable.
How many pieces do you want to order in total? You can use a precise number or one of the most common presets — from 15 to 1000 pieces.
T-shirt, hoodie, polo or jacket. The garment type influences the statistical curve — a hoodie fits differently than a t-shirt, which shifts how sizes distribute across the group.
Sports team, mixed office, university event, festival. The group profile shifts the curve — not every audience distributes the same way.
SizePlan calculates how many XS · S · M · L · XL · XXL · XXXL to order, with the peak size highlighted. Manually editable and downloadable as PDF.
The result is not a generic number — it's a complete table, size by size, with the suggested quantities based on the profile you chose. If something doesn't convince you, you edit the numbers directly.
You order on instinct, you end up with twelve XL and run out of M before you even start. Or you order a bit of everything and still come up short on the right sizes. It's a problem that affects event organizers, merch sellers, team kit buyers — anyone ordering custom apparel for a group of people they don't know.
Distributions are calculated on aggregated anthropometric data by demographic segment, based on European EN 13402 standards and industry studies. The values are statistical estimates — they don't replace collecting individual sizes, but they're a reliable starting point when collecting them isn't possible. If you can collect sizes one by one, use FitList →, our tool for participatory size collection from a group.
