How To Order Group T-Shirt Sizes? A Complete Guide

Steps to Order Group T-Shirt Sizes

Ordering custom group t-shirts can be seamless if approached methodically. Here are the practical steps to ensure accurate sizing and a smooth process:

 1. Collect Size Information

Start by asking group members for their preferred T-shirt sizes. Use surveys, forms, or emails to make data collection easy and efficient. For larger groups, consider categorising responses by gender or age to simplify analysis.

2. Use a Size Chart

Every brand has unique sizing, so refer to the specific size chart provided by your supplier. Share this chart with your group to help them choose accurately based on chest width, length, and other key measurements.

3. Plan for Size Variability

Order a few extra T-shirts in sizes you expect to be most common, like medium or large. This flexibility accommodates last-minute changes or unexpected attendees.

4. Review the Data Thoroughly

Review the information for gaps or inconsistencies once you’ve collected all the size preferences. Confirm unclear responses and ensure your final size distribution matches the group’s needs.

What Is the Best Formula for Group T-Shirts Size Orders?

Finding the right balance of t-shirt sizes for a group is essential to ensure everyone gets a proper fit. Using a percentage-based approach across all size options, from XS to 5XL, can guide your order and minimise guesswork.

General Size Distribution Formula

For a typical group, here’s a breakdown to help you allocate sizes effectively:

• XS (Extra Small): 2-3%
• S (Small): 10-12%
• M (Medium): 25-30%
• L (Large): 20-25%
• XL (Extra Large): 20-23%
• 2XL (Double Extra Large): 7-9%
• 3XL (Triple Extra Large): 3-5%
• 4XL & 5XL: 1%

Consider Event Type and Purpose

• Casual Gatherings: Sizes tend to follow general population trends.
• Sports Teams: Larger sizes may dominate, as participants often prefer looser fits.
• Formal or Fitted Wear: Groups may lean towards smaller or exact sizes for a tailored look.

What’s the Best Way to Determine Sizes for Your Order?

Determining sizes for your custom t-shirt order is straightforward when you apply percentage-based guidelines. You can achieve an accurate and inclusive distribution by taking the total number of t-shirts in your order and multiplying it by the recommended percentages for each size. 

Here’s how it works:

Example for a Larger Order (400 t-shirts)

Using percentage-based guidelines, each size is calculated as follows:

• XS (Extra Small) – 2%: 400 x 0.02 = 8
• S (Small) – 11%: 400 x 0.11 = 44
• M (Medium) – 27%: 400 x 0.27 = 108
• L (Large) – 22%: 400 x 0.22 = 88
• XL (Extra Large) – 21%: 400 x 0.21 = 84
• 2XL (Double Extra Large) – 8%: 400 x 0.08 = 32
• 3XL (Triple Extra Large) – 4%: 400 x 0.04 = 16
• 4XL & 5XL – 1%: 400 x 0.01 = 4

Example for a Smaller Order (50 t-shirts)

For smaller orders, the same formula applies:

• XS (Extra Small) – 2%: 50 x 0.02 = 1
• S (Small) – 11%: 50 x 0.11 = 6
• M (Medium) – 27%: 50 x 0.27 = 14
• L (Large) – 22%: 50 x 0.22 = 11
• XL (Extra Large) – 21%: 50 x 0.21 = 11
• 2XL (Double Extra Large) – 8%: 50 x 0.08 = 4
• 3XL (Triple Extra Large) – 4%: 50 x 0.04 = 2
• 4XL & 5XL – 1%: 50 x 0.01 = <1 (can be omitted or redistributed).

What Is the Average Size Distribution for Various Events?

When ordering t-shirts for groups, the size distribution can vary significantly based on the type of event and the group’s demographics. 

Here’s a breakdown of common size trends for different kinds of events:

For School-Aged Children

Children’s t-shirt sizes are smaller, with a higher need for XS and S sizes. Growth spurts and fabric shrinkage should also be considered:

• XS: 25-30%
• S: 40-45%
• M: 15-20%
• L: 5-10%

Larger sizes (XL and above) are typically not required unless ordered for teachers or staff.

For College/University Events

Youth trends often influence sizing preferences in university settings, with oversized fits being popular:

• S: 10%
• M: 30%
• L: 30%
• XL: 20%
• 2XL and larger: 10%

Include more medium and large sizes to accommodate the preference for looser, casual styles.

For Women-Only Events

Women’s events typically lean towards smaller and medium sizes, with some inclusion of larger sizes for comfort:

• XS: 5-10%
• S: 30-35%
• M: 35-40%
• L: 15-20%
• Larger sizes (XL and above): 5-10%

For Men-Only Events

Men’s events often require a broader range of larger sizes:

• S: 5-10%
• M: 25-30%
• L: 30-35%
• XL: 20-25%
• 2XL and above: 10-15%

This distribution works well for athletic or professional male-dominated groups.

For Mixed Groups

A balanced approach ensures inclusivity when the group includes both men and women:

• XS: 2-3%
• S: 12-15%
• M: 25-30%
• L: 25%
• XL: 20%
• 2XL and above: 5-8%

Unisex t-shirts are often the best choice for mixed groups as they provide a comfortable fit for everyone.

Common Mistakes to Avoid When Ordering Group T-Shirts

Ordering group t-shirts may seem straightforward, but even small oversights can lead to dissatisfaction or wasted resources. 

Here are the most common mistakes to avoid:

1. Ignoring Size Diversity

Groups often have participants with a wide range of body types. Failing to account for size diversity can result in t-shirts that don’t fit everyone, leaving some members feeling excluded.

2. Overlooking a Detailed Size Chart

Not using a brand-specific size chart can lead to incorrect size selections. Each brand has unique measurements, so using generic sizes can cause fit issues.

3. Forgetting to Include Buffer Sizes

Unexpected changes, like last-minute additions to the group or incorrect size data, are common. Skipping a buffer of extra sizes can leave you unprepared.

4. Misjudging the Group’s Demographics

Assuming a “one-size-fits-all” distribution can result in too many of one size and too few of another. Tailor the size breakdown to the group’s age, gender, and activity type.

5. Neglecting Fabric Considerations

Certain fabrics, such as 100% cotton, may shrink after washing. Ignoring this factor can result in t-shirts that fit initially but become too small after laundering.
