6'8" Cattle Trailer: The Standard-Width Workhorse
Before you spend money on a wider box, it's worth knowing what most ranchers actually run: a 6'8" wide cattle trailer. That's our standard interior width at Star Manufacturing, and for the vast majority of commercial cow-calf operations, stocker programs, and general-purpose hauling, it's the right width — enough room for cattle to travel comfortably in two rows without paying for interior space you don't need. Every 6'8" trailer we build in Wharton, TX gets the same 5/16" seam-welded frame and full hot dip galvanized finish as our wider builds, in lengths from 14' to 40'.
We also build 7' wide and 7'6" extra-wide trailers for bigger cattle, bulls, and bison. But if you're running commercial cows, stockers, or a mixed cow-calf herd, don't assume you need the upgrade — 6'8" is the width most working ranches actually order, and it tows lighter and parks easier than the wider boxes.

Why Most Ranchers Order Standard Width
- Lighter towing: A narrower box means less weight and less wind resistance behind your truck — meaningful on long hauls to auction or pasture.
- Easier to park and store: 6'8" fits in more barn stalls, sheds, and trailer parking spots than a 7'6" box.
- Right-sized for commercial cows: Most commercial cow-calf pairs and stockers don't need extra shoulder room — the standard width keeps them snug and stable in transit, which actually reduces shifting on the road.
- Lower cost: Standard width uses less material than the wide-body builds, which keeps the base price down without cutting corners on the frame or finish.
When to Size Up Instead
If you're running seedstock bulls, bison, or consistently large-frame cattle, don't force them into a standard-width box. See our tall cattle trailers page for height and our width pages above for shoulder room — both matter for big animals riding comfortably. For everything else, 6'8" is the proven, most economical choice.

Pair a standard-width trailer with the features that fit your operation: bar top or solid side panel configuration, slider gates for sorting, and rubber flooring for footing. Every configuration is available across the full 14'-40' size range, all hot dip galvanized as standard or available painted.
Frequently Asked Questions
Is 6'8" too narrow for full-grown cattle?
No — 6'8" is a full commercial standard width used across the livestock trailer industry and comfortably fits mature cows, stockers, and calves. It's only bulls, bison, and unusually large-frame cattle that typically benefit from a wider box.
Can I upgrade width later?
No — trailer width is set at the time of build. If there's any chance your herd will run larger animals down the road, talk to our team before ordering so we can help you decide between standard and wide-body up front.
Does standard width cost less than 7' or 7'6"?
Yes, generally. Less material and a lighter overall build typically keep the base price lower. Get an exact number for your configuration with our online quote builder.
