Rectangle Body Shape (Straight Shape): Measurements, Features, and Style Guide
A rectangle body shape, also called a straight shape, means your bust, waist, and hips are similar in width, and your waist is only slightly smaller. The easiest check: your bust and hips are within about 5% of each other, and your waist is less than about 25% smaller than your hips. This describes proportions only. It says nothing about your weight, fitness, or health.

A rectangle body shape is a body type where the shoulders, waist, and hips are about the same width. The waist is not strongly defined, so the outline looks straight and even from top to bottom, like a rectangle.
It is one of five common female body shapes. The other four are hourglass, pear (triangle), apple, and inverted triangle. In most guides and calculators, “rectangle”, “straight”, and “banana” mean the same shape. You may also see the pear and spoon body shapes mentioned. Both have hips that are wider than the bust, which is the opposite of a straight outline.
Rectangle Body Shape Measurements
There is no single official formula, and different calculators use slightly different numbers. A commonly used rule of thumb is:
Bust and hips
Within about 5% of each other.
Waist
Less than about 25% smaller than the hips (a waist-to-hip ratio above about 0.75).
Outline
Little curve between the bust, waist, and hips.
Here is a simple example
| Measurement | Example (inches) | Example (cm) |
|---|---|---|
| Bust | 35 | 89 |
| Waist | 29 | 74 |
| Hips | 36 | 91 |
In this example, bust and hips are close in size (35 and 36), and the waist is only a little smaller. This points to a rectangle shape. Not sure how to take your numbers? See our body measurement chart.
Close to the limit?
Borderline numbers can give different results on different tools. If your measurements are close to the limit, you may be between two shapes, and that is normal.
How to Know If You Have a Rectangle Body Shape
Check these signs:
Similar widths
Your bust, waist, and hips are close in size.
Small waist difference
Your waist is only a little smaller than your bust and hips.
Shoulders and hips
Your shoulders and hips are about the same width.
Even weight gain
You tend to gain or lose weight evenly across your body.
Straight lines
Your frame looks lean, straight, or athletic.
For an accurate result
Measure your bust at the fullest point, your waist at the narrowest point (usually just above the navel), and your hips at the widest point. Keep the tape snug but not tight, and don’t pull your stomach in. You can also use our body type calculator to get a result in a minute.
Rectangle vs Other Body Shapes
People often confuse the rectangle shape with similar ones. This table shows the key difference.
| Shape | Key difference from the rectangle |
|---|---|
| Hourglass | Bust and hips are about equal, with a clearly smaller waist |
| Triangle / Pear | Hips are clearly wider than the bust, with a defined waist |
| Spoon | Hips are wider than the bust, with a higher, shelf-like curve at the sides and a defined waist |
| Apple | Weight sits mostly around the middle, with extra fullness at the midsection |
| Inverted triangle | Bust or shoulders are clearly wider than the hips |
Rectangle vs hourglass: Both have similar bust and hip sizes. The difference is the waist. A rectangle has a waist close to the bust and hips, while an hourglass has a clearly smaller waist.
Rectangle vs apple: Both have a less defined waist. An apple carries fullness around the midsection. A rectangle is straight and even from top to bottom.
Rectangle vs pear and spoon: A pear and a spoon both have hips that are clearly wider than the bust, and a defined waist. A rectangle has bust and hips of similar width, with little waist definition.

Best Clothes for a Rectangle Body Shape
The goal is to add shape and define the waist, or to enjoy the clean, straight lines of your frame. These are suggestions, not rules. Wear whatever makes you feel comfortable.
Tops and Dresses
- Peplum tops and ruffled styles add curves at the waist.
- Wrap dresses and fit-and-flare dresses create a defined waist.
- Empire waists and belted styles mark the middle.
- Details at the shoulders or bust, such as ruffles or prints, add shape on top.
- Layering, such as a fitted jacket over a top, builds dimension.
Bottoms
- High-waisted trousers and skirts with a belt mark the waist.
- A-line, flared, and pleated skirts add volume at the hips.
- Bootcut and flared jeans balance a straight frame.
- Pockets, patterns, and textures on the bottom half add curves.
Fit Tips
The most common problem for this shape is clothing that falls straight and looks boxy, with no shape at the waist. To fix this:
- Choose cuts with a defined waist, such as wrap or tie styles.
- Add a belt to dresses, coats, and oversized tops.
- Pick clothes with texture, pleats, or layers for extra dimension.
- Check the brand’s measurement chart before buying online.
What to Be Careful With
Very straight, boxy, or shapeless pieces can make the outline look even straighter. That is not wrong. It is a clean, modern look that many people love. Add a belt or a fitted layer if you want to show your waist.
Fitness and Health Tips
Body shape is mostly decided by your bone structure, genetics, and where your body stores fat. Exercise cannot change your skeleton, but it can change how strong and toned you feel.
Simple habits
- Mix strength training for your whole body with cardio you enjoy.
- If you want more curves, build the shoulders, glutes, and legs with strength exercises.
- Include core exercises like planks to support your posture and back.
- Don’t try to “fix” your shape. Aim for strength, energy, and comfort.
A rectangle shape does not mean you are healthy or unhealthy. Health depends on many things such as diet, activity, sleep, and medical history. If you have health concerns, speak with a qualified healthcare professional.
Can Your Rectangle Shape Change?
Yes. Your skeleton stays the same, but your proportions can change with weight gain or loss, muscle building, pregnancy, hormonal changes, and ageing. Recheck your measurements every three to six months if your body is changing.
