Correct size for knit and crochet tops

Why doesn't my knitted or crocheted top fit properly?

Many people know the problem: a project is finished, looks perfect at first glance, and yet something is not quite right. It fits too tightly across the chest, slips off the shoulder, looks misshapen, or simply doesn't feel as comfortable as it should.

The cause rarely lies in the handiwork itself or the pattern. Far more often, the problem arises because the size was not properly adapted to the body and the material.

And so that these uncertainties do not arise in the future, you will now learn everything about the perfect fit for your next top.

 

General sizes for women's tops

Women's clothing in Europe is categorized in standard sizes from approximately 32 to 60. These sizes are based on average values and serve as an initial guide.

However, since every body is built differently, the same size can fit two people differently, depending on shoulder width, bust shape, and proportions.

 

How to find your suitable size

The most important foundation is the chest circumference. For most tops, it determines the correct size. Additionally, shoulder and body measurements can help to classify the fit more accurately.

A detailed size chart will help you to reliably determine your measurements. The table is the basis for all Fräulein Gerda designs.

Why size in knitting and crochet is not a fixed value

In contrast to ready-to-wear clothing, a size like 38 or 42 is not a fixed standard, but only a starting point.

A finished project always results from the interaction of several factors:

• Body measurements
• Gauge
• Construction
• Ease
• Material behavior after washing

Even small deviations are enough for two projects using the same pattern to turn out differently.

 

Body measurement vs. finished measurement - the most important difference

A common misconception is that the pattern corresponds directly to the body. In fact, however, a distinction is always made between two values:

The body measurement describes your actual circumference, while the finished measurement is the knitted or crocheted result. In between lies the so-called ease or comfort allowance.

-> Exactly this range determines the fit. My patterns always state the finished measurement.

 

Ease - why a few centimeters change everything

The ease/comfort allowance determines how a top hangs on the body. It is one of the most important control factors for the fit. 

• 0 - 5 cm: body-hugging
• 5 - 10 cm: classic, comfortable fit
• 10 - 20 cm: loose to oversized

 

Knitting and crochet - why the technique changes everything

The chosen technique influences the fit more than many think.

• Knitting: Here, the shape is created by elastic stitches. Decreases, increases, and short rows ensure that the material adapts well to the body. Result: soft, flexible, flowing
• Crochet: Here, the shape is created by a more stable structure of rows, surfaces, or modules. Result: shape-retaining, clear, less stretchy

 

Construction and shoulders

Why the shoulder has more influence than many think

If a knitted or crocheted top does not sit correctly despite being the right size, the cause is often not the chest circumference or the chosen ease. The shoulder often plays a decisive role.

The shoulder forms the foundation for the entire fit. From here, the sleeves, neckline, and upper body extend. If this area is not optimally constructed, a top can pull, slip, or drape differently than planned, even if the other measurements are correct.

Both in knitting and crocheting, there are different shoulder and sleeve constructions. These include, for example, raglan, circular yoke, set-in sleeves, dropped shoulders, or saddle constructions. Each variation distributes width and freedom of movement slightly differently and thus influences the later fit of the top.

Especially with crochet projects, the shoulder should not be underestimated. Since crocheted fabrics are usually less elastic than knitted ones, small deviations often have a greater effect on the fit.

 

The construction influences the fit

By construction, I mean how a top is built and worked. It determines where increases and decreases occur, how sleeves and shoulders are created, and how the fit is distributed over the body.

The construction, therefore, does not determine the size itself, but rather how this size sits on the body in the end.

A simple example: Two sweaters can have the same chest circumference and thus theoretically be the same size. Nevertheless, they can look completely different. One hangs loosely and comfortably, the other sits rather close to the body or emphasizes the shoulders more strongly.

The reason for this lies in the construction!

 

All important data at a glance

That is exactly why I developed a practical data sheet. On two pages, you can clearly enter and permanently document all important information about your project.

The data sheet is available in a version for knitting projects and for crochet projects, so that the particularities of both techniques can be taken into account.

Especially practical: The data sheet is perfect for your personal collection folder. This way, you have your measurements, calculations, and project data ready at hand at all times and can draw on previously collected experience for future tops.

Over time, this creates a valuable personal fit collection that helps you to coordinate sizes and adjustments better and better to your own needs.

 

How to adjust every pattern to your own body size

More space in the chest and bust area

If the width in the chest area is not sufficient, additional increases can be worked under the arms or along existing increase lines.

In top-down constructions, this is often done after separating the body and sleeves. This creates additional width exactly where it is needed, without changing the shoulders or neckline.

The number of stitches required for this can be calculated using the gauge.

Example: Your gauge results in 20 stitches per 10 cm. You want to achieve a total of 5 cm more width in the chest circumference. At this gauge, 5 cm corresponds to 10 stitches. Since the front and back should be adjusted evenly, these 10 stitches are distributed on both sides.

This allows you to calculate how many additional increases are necessary before you start.

More freedom of movement in the arm area

If tops pull under the arms or the sleeves seem too tight, it is often not the total width that is missing, but the depth of the armhole.

In this case, additional rows or rounds can be worked before separating the body and sleeves. This creates more space in the armpit area and significantly improves the freedom of movement.

Adjustments for wider or narrower shoulders

If the shoulders are not in the right place, you should not automatically choose a different size.

It is often enough to adjust the shoulder width or choose a different construction. Especially raglan, circular yoke, dropped shoulders, or set-in sleeves react differently to changes in the shoulder area.

More width at the waist or hips

Many women require different sizes for their bust, waist, and hips.

Through targeted increases or decreases between the bust, waist, and hips, the silhouette can be shaped individually. For example, you can work size 44 in the bust area and size 46 in the hip area without having to knit or crochet the entire top a size larger.

Adjusting the length individually

The body length is also only considered as an average in many patterns.

Anyone with a longer or shorter torso can work additional rows or rounds before the waist, hips, or hem. The same applies to sleeves.

If, for example, you achieve 28 rows per 10 cm and want to make your top 5 cm longer, you will need about 14 additional rows.

💡 Most adjustments only affect individual areas of the top. Often, a few additional stitches or rows are enough for a model to fit significantly better and suit your own proportions.

 

An important change of perspective

When a knitted or crocheted top does not fit properly, the pattern or the designer is often blamed first. However, a pattern is not an exact blueprint for every individual body shape, but always a starting point based on average measurements and typical proportions. One's own body almost always deviates from this in several points. That is precisely why a project can turn out differently than expected despite correct execution.

Instead of asking "Why doesn't the pattern fit?", it is often more helpful to ask: "Which parts do not fit my body and how can I adjust them?"

Many patterns are rated critically online very quickly, sometimes even with very harsh comments. This is exactly one of the reasons why I personally hesitated for a long time to design tops. Because you actually know: It will never fit 100% perfectly for every person, our bodies are simply too different for that.

💛 And that is exactly the decisive point:
It is not the perfect pattern that makes a good top, but the understanding of how to adapt it to your own body.
