Children’s shirt

PDF patterns for children’s shirts: choosing the right pattern to sew a shirt that lasts

A children’s shirt pattern is often the project that gets you into regular sewing: the result is immediately useful, the fabric budget remains reasonable (0.8 to 1.2 m for a size 4), and the finished garment holds its shape better than a shop-bought one if you choose your fabrics carefully. The PDF patterns in this collection cover sizes 2 to 12 years, with options for a classic collar, mandarin collar, blouse-style collar or no collar, depending on the design.

Which fabric should you use to sew a durable children’s shirt?

Cotton poplin at 80–90 g/m² remains the go-to choice for a smart shirt or one for the start of the school year: it irons easily, withstands repeated washes at 40°C without distorting the buttonholes, and cuts cleanly. For a casual shirt worn all summer long, chambray at 120–130 g/m² offers a nice drape without being heavy. Double gauze is suitable for children with sensitive skin but requires flat seams (English seams or folded seams) as it frays quickly.

To avoid on a child’s shirt: pure linen weighing less than 200 g/m² (too fragile around the buttonholes after 10 washes) and braided synthetics, which trap heat around the collar. If you’re looking for a children’s Hawaiian shirt for the holidays, a printed cotton at 100–110 g/m² with a good weight holds up well and remains machine-washable.

Construction details: what makes a children’s shirt hold its shape

The side seams of a child’s shirt are subjected to stresses that those of an adult’s shirt are not: pulling at the back, sliding on grass, and being used as a makeshift rucksack. A 1.5 cm flat-fell seam on the sides doubles the strength without adding bulk. Most patterns in this collection explicitly state the recommended type of seam in the instructions.

The spacing between buttons on a boy’s or girl’s shirt is calculated differently depending on age: 5.5 cm between buttons for a size 4, 6.5 cm for a size 8, compared with 8 to 9 cm on an adult shirt. A well-designed pattern incorporates this calculation into the cutting plan. Check that the recommended buttons are 11 mm or 13 mm (not 15 mm), as these are easier for a child to handle on their own.

Children’s shirt patterns: classic collar, Mao collar or Peter Pan collar

The classic collar with a collar stand is the most technically challenging but also the most durable: the double layer retains its shape even after 50 machine washes. The Mao collar (a 3 cm straight strip) is quicker to assemble and is ideal for summer shirts or for seamstresses new to this style. The Peter Pan collar, on the other hand, is better suited to girls’ shirts with a more rounded silhouette.

Designers such as Klafoutis, Le Papa de Jojo or Lilikou offer children’s shirt patterns with several collar variations included in the same PDF file, which saves you from having to buy two different patterns to try out both finishes.

How to choose the size for a children’s shirt PDF pattern

Chest circumference takes precedence over the age indicated: a 6-year-old child with a chest circumference of 60 cm will not fit into a ‘6-year-old’ pattern designed for 57 cm. Always measure the chest circumference, hip circumference and shoulder-to-shoulder length before printing. For multi-size PDF patterns, trace directly onto the digital file using PDF reader software before printing to ensure you only keep your size and avoid confusion between the cutting lines.

The seam allowance included varies depending on the designer: 1 cm for most French brands in this shop, 0.6 cm (3/8″) on some patterns of Anglo-Saxon origin. Checking this in the instructions before cutting will prevent any unpleasant surprises when it comes to assembly.

• Chest measurement + 8 to 10 cm ease for a shirt worn over a T-shirt
• Chest measurement + 6 cm for a fitted shirt worn on its own in summer
• Back length: measure from the nape of the neck to the waist, add 8 to 12 cm depending on the style

Boys’ shirts or girls’ shirts: are they really that different?

Technically speaking, a boy’s shirt and a girl’s shirt differ mainly in the direction of the button placket (right for boys, left for girls according to European convention) and the width at the shoulders. Some patterns in this collection are unisex, with a note on the buttoning direction. Others are designed specifically: children’s blouses often feature variations with ruffles or embroidered collars designed for girls, whilst checked shirts or shirts with a breast pocket are aimed more at boys.

The children’s Hawaiian shirt, on the other hand, is entirely unisex: with a camp collar (an open collar that lies flat), it is cut from printed fabric without regard to gender.

Completing the homemade wardrobe: what goes with a children’s shirt

A PDF pattern shirt is often sewn in batches: same fabric, different sizes if you have several children. To complete the wardrobe, the children’s trousers and children’s jackets from the shop often share the same construction techniques. Children’s pyjamas frequently include a buttoned nightshirt version that uses exactly the same collar and buttonhole techniques.

If you’re new to making children’s shirts, start with a collarless style featuring a faceted neckline: the construction is essentially the same, but you’ll skip the collar stage, which accounts for 80 per cent of the difficulty. Once you’re comfortable with this, moving on to a classic collar takes just an extra hour and the results are dramatically different.

What size buttons should you use for a child’s shirt?

For a child’s shirt for ages 2–6, 11 mm buttons are suitable for the cuff and collar buttonholes. For ages 7–12, use 13 mm buttons on the front. Avoid fragile pearlescent buttons on garments that are washed regularly: resin or polyester buttons are more resistant to machine washes at 40°C.

How much fabric do you need to sew a child’s shirt?

Allow 0.8 m to 1.0 m of fabric, 140 cm wide, for a 2–4-year-old, 1.0 m to 1.2 m for a 6–8-year-old, and 1.2 m to 1.4 m for a 10–12-year-old. Add 20 cm if you’re planning to include a contrasting collar or pockets made from a different fabric. Poplin costs between €5 and €12 per metre, depending on the quality.

Can you sew a child’s shirt on an entry-level sewing machine?

Yes, without any restrictions. A child’s shirt does not require an overlocker: zigzag stitches are sufficient to finish the edges, and the folded seams can be sewn entirely with a standard presser foot. A machine with a regular straight stitch and a zigzag stitch can handle 100 per cent of the construction.

How do you adapt an adult shirt pattern to a child’s size?

This is not recommended. The proportions between the shoulders, armholes and torso length are fundamentally different between children and adults. An adult pattern scaled down results in an armhole that is too high and a back that is too long. The patterns in this collection are designed specifically for children’s body shapes: use them as they are.
