Fabletics
Here’s how Fabletics fits your child compared to other brands you might be considering, so you know before it’s in your cart.
Find your child’s size in Fabletics
Enter your child’s measurements once — we’ll size them in Fabletics and at 100+ other brands, each from that brand’s own published chart. Height and weight are required; add chest, waist, hips and inseam to sharpen the fit.
Fabletics publishes one unisex chart, so that is what we size against.
Your child wears one size in Fabletics. What should you buy elsewhere?
Pick the size your child wears at Fabletics to see which brands have the same label and measurements (twins) and which run shorter or longer (strangers) — based on each brand’s own chart.

In short
Where labels drift. The exceptions are the “strangers” above — e.g. at size 8, Il Gufo, Bonpoint, U.S. Polo Assn. cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a Fabletics number is a safe bet elsewhere — measure once, then double-check only the handful of “stranger” brands above.

Fit & the transitions that trip parents up
Fabletics-specific things the size number alone won’t tell you — drawn from its own charts.
Runs true to size
Order your child's usual size; the joggers are the one piece a few parents found snug.
A new, small unisex line
A unisex Go-To hoodie, crew and jogger range in 2T through 18 — recent and limited, so shopper feedback is still thin.
Specialty & inclusive fits
Which trimmer, roomier, or adaptive cuts Fabletics publishes alongside its standard sizes.
What shoppers say about the fit
Community consensus
Shopper opinion · not Little & Youth’s measurementThis is what parents report anecdotally — crowd sentiment, not a Little & Youth determination. Our sizing above is computed from Fabletics’ own published chart; the notes here come from public parent discussion.
Fabletics kids runs true to size — order your child’s usual size, with the joggers the one piece a few parents found snug. The kids’ line is new (late 2024) and small — a unisex Go-To hoodie, crew, jogger and holiday onesie in 2T through XXL (18) — so shopper discussion is limited to the reviews on Fabletics’ own site, where roughly 175 parents and grandparents mostly report ‘fits great’ or ‘true to size’; the fit comments that go the other way are a toddler whose 3T hoodie was outgrown in three wears, a jogger buyer who had to reorder a size up for a snug waist, an XXL jogger ‘a little on the small side’, one ‘shorter than hoped’, and two crews ‘a tad big’ on a child at the bottom of the size band. Reviewers describe the fabric as thick, soft, warm and the same quality as the adult line, and the hoodie is cut a bit wide on purpose. The r/Fabletics community has asked how kids’ sizes compare to Cat & Jack and Gap and got no answers, so there is no independent cross-brand read yet.
Based on anecdotal discussion from multiple publicly available online sources; your experience may differ.
Should you buy Fabletics?
Consider it if…
- You want matching family sets — nearly every reviewer bought the kids' hoodie, crew or holiday onesie to match a parent or grandparent, and the prints line up with the adult range.
- Your child has sensory issues or lives in soft sweats — parents say the fleece is thick, warm and soft enough that kids refuse to take it off, and the joggers hold up to play and washing.
- You are a VIP member shopping the sales — kids' pieces regularly drop to a few dollars in member promos, which is when most reviewers bought.
Think twice if…
- You are not a member — non-member prices run about $55 for kids' joggers, and the VIP model means a monthly charge unless you skip.
- Your child is at the top of a size band — the bands are wide (S 6/7, M 8, L 10/12) and the few 'snug' and 'outgrown fast' reports came from kids near the upper edge; consider the next size.
- You want range or basics beyond sweats — the kids' line is a handful of unisex fleece pieces and seasonal onesies, and parents repeatedly ask for more options.
Skip the cross-referencing — let Little & Youth do it.

Does Fabletics kids run small or big?
True to size, by most on-site reviews — 'fits TTS' and 'perfect fit' dominate. The minority reports lean small (a snug jogger waist, a 3T hoodie outgrown quickly, an XXL 'a little on the small side'), so a child at the top of a band is safer one size up; two crew buyers found the 4T/5T a tad big on a 3T-4T child.
How do Fabletics kids sizes compare to Target or Gap?
Unknown from shopper data — a parent asking exactly this on r/Fabletics got no replies. The bands are height-and-weight based and unisex, so compare the chart's measurements rather than the age label; the 4T/5T, 6/7 and 8 sizes map roughly to standard US kids' sizes in reviewer comments.
Are the kids' pieces the same quality as adult Fabletics?
Reviewers say yes — 'as high quality in youth as on adult', thick fleece that keeps warmth without a jacket, washes well. The one recurring durability complaint is a jogger drawstring breaking after a few washes.
What measurements do I need to size Fabletics accurately?
Fabletics publishes height, weight, chest, waist, hip in its size chart. Height is the primary driver, and the chest/waist figures let you confirm body fit for a child between sizes.
Where do I buy Fabletics?
Fabletics is sold on its own site and through select retailers.
