Here’s how F&F (Tesco) fits your child compared to other brands you might be considering, so you know before it’s in your cart.
Find your child’s F&F (Tesco) size on the left. Twins wear the same number the same way — your size carries straight over. Strangers use the same number but cut it shorter or longer, so don’t trust the label alone.

Sizes shown use F&F (Tesco)’s girls’/unisex chart where the brand splits by gender; boys’ sizes at the same number can run slightly taller.
Where the number just works. At up to 1 month, up to 3 months, 0-6 months, 6-9 months, 9-12 months, 6-18 months and more, F&F (Tesco) lines up with every brand we track — the size carries straight over.
Where labels drift. The exceptions are the “strangers” above — e.g. at size 2-3 years, Primary, Ziggy Zaza, Rylee + Cru cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a F&F (Tesco) number is a safe bet elsewhere — measure once, then double-check only the handful of “stranger” brands above.

Which trimmer, roomier, or adaptive cuts F&F (Tesco) publishes alongside its standard sizes.
This is what parents report anecdotally — crowd sentiment, not a Little & Youth determination. Our sizing above is computed from F&F (Tesco)’s own published chart; the notes here come from public parent discussion.
F&F’s fit splits by age. Its baby clothes lean small and slim: on Mumsnet, parents call Tesco baby clothes small, snug or slim more often than big, several say they suit long, slim babies, and one notes the earliest sizes are short in the leg. Its school uniform runs true to generous: in a 2018 Mumsnet product test of F&F uniform (brand-supplied, so not independent), most of the 24 reviewers said it fit well, a few found it big or baggy and none found it small; older threads complain about roomy waists, and adjustable waistbands are the usual fix. Which?’s 2026 school-uniform survey gave Tesco (F&F) 4 of 5 stars for fit. In the wash, most reviewers say it holds up and stains come out, with a couple reporting polo shirts shrinking at 40°C and one parent seeing baby clothes shrink lengthwise. F&F’s online shop delivers within the UK only.

It’s an age band, not a measurement. F&F’s size guides pair each age band with a body height and chest (and waist for uniform). Children of the same age vary, so compare your child’s measurements to the chart rather than going by age alone.
No. Tesco’s F&F help page says: ‘Currently, we only deliver within the UK, excluding the Channel Islands and British Forces PO addresses.’
Not online — F&F’s online delivery is UK only. F&F is sold in some Tesco stores in Ireland, such as the Santry superstore in Dublin.
Most reviewers say it washes well and stains come out. The exceptions: a couple of parents saw polo shirts shrink at 40°C, and one found baby clothes shrank lengthwise.
F&F (Tesco) publishes height, weight, chest, waist in its size chart. Height is the primary driver, and the chest/waist figures let you confirm body fit for a child between sizes.
From the bigger sizes up, F&F (Tesco) publishes separate girls’ and boys’ charts, so the same number can differ by gender. The figures on this page use F&F (Tesco)’s girls’/unisex chart.
F&F (Tesco)’s socks are sized by shoe size, not age — buy for your child’s current shoe size, and if they fall between two ranges choose the smaller so the sock stays up. See how every kids’ shoe brand runs and how wide each is cut on our kids’ shoe sizing guide.
F&F (Tesco) is sold on its own site and through select retailers.
