Guide to Men's Suit Sizes When Buying in Bulk

When it comes to purchasing men's suits in bulk, whether for a retail store, rental service, or corporate uniform program, understanding sizing is absolutely crucial. Buying the wrong sizes can lead to poor customer experience, increased returns, and wasted inventory. At Wessi Wholesale, we specialize in providing premium men’s suits, blazers, and shirts in bulk—and we know that a strong grasp of sizing ensures a smooth wholesale buying process.

This comprehensive guide will walk you through everything you need to know about men’s suit sizes, helping you make smarter, more efficient bulk purchasing decisions.

1. The Basics of Men's Suit Sizing

Men’s suits typically consist of two main components: the jacket and the trousers. Suit sizes are usually indicated with a number and a letter—for example, 40R or 52L—where the number refers to the chest measurement (in inches or centimeters, depending on region) and the letter indicates the length of the jacket.

• Short (S) – for men under 5’8” (172 cm)

• Regular (R) – for men between 5’8”–6’0” (172–183 cm)

• Long (L) – for men over 6’0” (183 cm)

At Wessi Wholesale, we offer a wide range of sizes that cater to different body types, ensuring that our wholesale clients can meet the needs of a diverse customer base.

2. Understanding Size Conversion Charts

One of the challenges in buying suits in bulk, especially internationally, is navigating between different sizing standards—US, UK, EU, and Asian sizes. Make sure to reference a reliable conversion chart and confirm the sizing system used by your supplier.

For example:

• US 40R = EU 50R

• US 42L = EU 52L

Wessi Wholesale provides clear size charts and measurement guides with every collection to simplify bulk ordering for our clients around the world.

3. Key Measurements You Should Know

When bulk buying, it’s essential to understand which measurements most impact fit. Here are the most important ones:

• Chest size – The primary number in the size label

• Waist size – Typically 6 inches less than chest size (known as the “drop”)

• Sleeve length – Impacts arm fit and jacket length

• Shoulder width – Crucial for jacket structure

• Inseam – Important for trouser length

Our suits at Wessi Wholesale follow standard industry drops, usually 6” from chest to waist. For example, a 40R jacket comes with 34” trousers. We also offer flexible drop options for specific bulk orders.

4. Offering a Balanced Size Breakdown

One of the most common mistakes in wholesale suit purchasing is ordering too many of one size. A good size breakdown ensures you meet demand across different customer types.

Here’s a sample size ratio for a standard 12-piece pack:

• 1 x 38R

• 2 x 40R

• 3 x 42R

• 3 x 44R

• 2 x 46R

• 1 x 48R

At Wessi Wholesale, we can customize bulk size packs depending on your customer demographic. This reduces overstocking and maximizes sell-through.

5. Don’t Forget About Fit Types

Modern menswear isn’t one-style-fits-all. Suits now come in various fits:

• Slim Fit – Contoured for a modern, sleek silhouette

• Regular Fit – Classic shape, more room in chest and waist

• Relaxed Fit – Looser for comfort and mobility

Wessi Wholesale offers all three fit options in our bulk collections, allowing you to mix and match based on your retail or rental needs.

6. Simplify with Sample Sets

If you're new to wholesale or bulk suit buying, consider ordering a sample size set before committing to large quantities. This helps you physically review quality, sizing accuracy, and customer response.

We offer sample kits at Wessi Wholesale, so you can test different sizes and fits before placing your full order.
