How Many Pallets Fit on a Trailer? All Sizes Compared
How many pallets fit on a trailer depends on the size: a 28-foot pup holds 14, a 48-foot holds 24, a 53-foot holds 26. Full comparison across all standard trailer sizes — dimensions, loading patterns, weight limits, flatbed differences, and a decision guide for choosing the right trailer.
How many pallets fit on a trailer? The short answer: 14 on a 28-foot pup, 24 on a 48-foot, and 26 on a 53-foot — all floor-loaded with standard 48×40 GMA pallets. Loading pattern, pallet size, and weight limits all change those numbers. Here is the complete breakdown.

Pallet Capacity by Trailer Size — Full Comparison
| Trailer | Usable Length | Standard | Turned | Double Stack | Payload |
|---|---|---|---|---|---|
| 28-ft pup | 330" | 14 | 16 | 28 | ~24,000 lbs |
| 48-ft dry van | 576" | 24 | 28 | 48 | ~45,000 lbs |
| 53-ft dry van | 636" | 26 | 28–30 | 52 | ~48,000 lbs |
| 48-ft flatbed | 576" | 24 | 28 | Weight-limited* | ~48,000 lbs |
| 53-ft flatbed | 636" | 26 | 28–30 | Weight-limited* | ~48,000 lbs |
| Two 28-ft (doubles) | 660" | 28 | 32 | 56 | ~48,000 lbs |
*Flatbed stacking limited by weight and tie-down requirements, not interior height. All counts based on 48×40 GMA pallets. Standard = 48" side faces trailer length. Turned = 40" side faces trailer length.
The Math — Why Each Trailer Gets That Number
Every pallet count comes from two calculations: how many pallets fit across the width, and how many rows fit along the length.
Usable interior width: 98"–99"
Two 48" pallets side by side: 96" ✅ fits with 2"–3" clearance
Three 48" pallets: 144" ✗ does not fit
→ All standard dry vans load 2 pallets wide
28-foot:
Usable length ~330" ÷ 48" = 6.875 → 7 rows (nominal fit) × 2 = 14 pallets
Turned (40" faces length): 330" ÷ 40" = 8.25 → 8 rows × 2 = 16 pallets
48-foot:
Usable length 576" ÷ 48" = 12 rows × 2 = 24 pallets
Turned (40" faces length): 576" ÷ 40" = 14.4 → 14 rows × 2 = 28 pallets
53-foot:
Usable length 636" ÷ 48" = 13.25 → 13 rows × 2 = 26 pallets
Turned (40" faces length): 636" ÷ 40" = 15.9 → 15 rows × 2 = 30 pallets (pinwheel max)
Loading Patterns — How They Change the Count
The same trailer can hold different pallet counts depending on how you load it. Three patterns apply across all trailer sizes:
Standard (straight) loading — baseline count
All pallets loaded with the 48-inch side facing the trailer length. Two columns across the full width. Default for all LTL shipments — carriers consolidate multiple shippers' freight and need consistent, predictable placement. Gives 14 / 24 / 26 pallets depending on trailer size.
Best for: all LTL shipments, mixed loads, dock-constrained facilities
Turned loading — +2 pallets on any size
All pallets rotated 90° so the 40-inch side faces the trailer length. Shorter rows mean more rows fit in the same floor length. Adds 2 pallets over standard on a 28-foot (16 total), and reaches 28–30 on a 53-foot. Requires consistent pallet dimensions throughout.
Best for: dedicated FTL loads where maximising pallet count matters
Pinwheel loading — maximum floor count
Alternating pallets rotated 90° to interlock and recover space between rows. On a 53-foot trailer reaches 28–30 pallets. Requires careful pre-loading planning and consistent pallet dimensions. Not suitable for LTL — used for FTL when the extra positions justify the loading complexity.
Best for: FTL loads at or near capacity where 2–4 extra positions make a cost difference
Double stacking — doubles the count
A second pallet layer on top of the first. Doubles capacity on any trailer size. Three requirements: pallet height 48" or less per layer (to stay within 110" interior height), freight that can support weight above it, and total load within payload limits. Common for consumer goods, apparel, and light manufacturing.
Best for: lightweight, stackable freight on dedicated lanes — not suitable for fragile or top-heavy loads
💡 Which pattern to use
LTL: always use standard straight loading. FTL: if you're 1–2 pallets short of a full load, ask your driver or 3PL about turned or pinwheel loading before you load — it costs nothing and may save you a second trailer. Use the free load planner to visualise your configuration first.
Weight Limits — The Other Constraint
Pallet count is the floor space constraint. Weight is the other limit — and on a fully loaded trailer they can come into conflict. A 53-foot trailer fits 26 pallets by floor, but 26 pallets averaging 1,900 lbs each is 49,400 lbs — over the usable payload limit.
| Trailer | Usable Payload | Standard Pallets | Max avg lbs/pallet | Notes |
|---|---|---|---|---|
| 28-ft pup | ~24,000 lbs | 14 | ~1,700 lbs | Weight limit hit before floor fills on dense freight |
| 48-ft dry van | ~45,000 lbs | 24 | ~1,875 lbs | Slightly lower payload than 53-ft due to heavier trailer tare |
| 53-ft dry van | ~48,000 lbs | 26 | ~1,846 lbs | Federal GVW 80,000 lbs; ~48k usable after tractor + trailer tare |
| 53-ft flatbed | ~48,000 lbs | 26 | ~1,846 lbs | Same weight limit; lighter tare can yield slightly more payload |
⚠️ Always check both constraints
Floor space sets the maximum pallet count. Weight limits set whether you can reach it. For freight averaging over ~1,700 lbs per pallet on a 28-foot, ~1,875 lbs on a 48-foot, or ~1,846 lbs on a 53-foot, you will hit the weight limit before the floor fills. Verify with your carrier before booking.
Dry Van vs Flatbed — Pallet Count Differences
Flatbed trailers have identical floor dimensions to their dry van equivalents — a 53-foot flatbed has the same 636-inch length and 99-inch usable width as a 53-foot dry van. Floor pallet counts are therefore the same: 26 on a 53-foot flatbed, 24 on a 48-foot flatbed.
The difference is height and access. A dry van has a 110-inch interior height ceiling. A flatbed has no roof — but bridge clearances (13’6" from road, minus ~52-inch deck height) leave roughly the same 110 inches of usable load height for standard freight. For pallet counts, dry vans and flatbeds are equivalent.
Where flatbeds differ
No weather protection — freight must be tarped or inherently weatherproof. Tie-down requirements add loading time. Oversize loads that can't fit inside a dry van move on flatbeds. For standard palletised goods going into a warehouse dock, a dry van is almost always preferable.
When flatbeds carry more
For freight that can be triple-stacked — steel coils, lumber, concrete blocks — flatbeds carry significantly more volume per load. The constraint shifts to weight (48,000 lbs usable) and whether the freight can be secured safely without enclosing trailer walls.
How to Choose the Right Trailer Size
The right trailer comes down to pallet count, freight weight, destination dock restrictions, and whether you're shipping LTL or FTL. Here is a simple decision framework:
1–9 pallets — LTL on a 53-foot
Ship LTL. You'll share a 53-foot trailer with other shippers and pay by weight and linear feet. Watch the 12-foot rule — 5–6 pallets triggers a capacity surcharge.
10–14 pallets — compare LTL vs dedicated 28-foot pup
At this count, LTL pricing often exceeds the cost of a dedicated 28-foot pup (PTL). Get both quotes. A 28-foot also works for urban delivery where a 53-foot can't maneuver.
15–24 pallets — 48-foot or 53-foot FTL
Full truckload. Use a 53-foot for US domestic lanes. Use a 48-foot for Canada-US cross-border or dock-constrained destinations. Verify dock restrictions before booking.
25–26 pallets — 53-foot FTL
Standard 53-foot FTL. Most cost-effective for near-full truckload US domestic freight under 48,000 lbs.
27–30 pallets — turned/pinwheel loading or doubles
Ask about pinwheel or turned loading on a 53-foot — it can fit 28–30 pallets at no extra cost if freight allows. Or use a doubles combination (two 28-foot pups) for 28 combined pallets with independent spotting at the destination.
The 12-Foot Rule — Applies on Every Trailer Size
Regardless of trailer size, LTL carriers apply the 12 linear foot capacity rule the same way. Once your shipment occupies 12 or more linear feet of trailer floor space, a capacity surcharge applies — even on a 28-foot pup where 12 feet is nearly half the trailer floor.
The threshold is always the same: 3 rows of standard 48×40 pallets (5–6 pallets) equals 12 linear feet and triggers the charge on any trailer size.
⚠️ 12-foot rule — all trailer sizes
3 rows × 40" = 120" = 10 linear feet, rounded to 12 by most carriers. Applies equally on 28-foot, 48-foot, and 53-foot trailers. On a 28-foot pup, hitting the 12-foot threshold means your shipment is using 44% of the trailer floor — and still triggers the surcharge.

48-Foot Trailer Interior Dimensions
The 48-foot trailer is the predecessor to the now-dominant 53-foot trailer. While less common for domestic US freight, it's widely used in Canada-US cross-border lanes where provincial road regulations historically limited trailer length to 48 feet, and in dedicated fleet operations where loading docks were built to 48-foot specs.
| Dimension | 48-foot dry van | 53-foot dry van | Difference |
|---|---|---|---|
| Interior length | 576" | 636" | 60" shorter |
| Usable width | 98" | 99" | 1" narrower |
| Interior height | ~110" | ~110" | Same |
| Standard pallets | 24 | 26 | 2 fewer |
| Max payload | ~45,000 lbs | ~45,000 lbs | Same |
| Cubic capacity | ~2,600 ft³ | ~2,880 ft³ | ~280 ft³ less |
Pallet Count by Configuration — 48-Foot Trailer
| Pallet type | Size | Floor-loaded | Double stacked | Notes |
|---|---|---|---|---|
| GMA standard | 48" × 40" | 24 | 48 | 2 wide, 12 rows. Most common US pallet |
| Square pallet | 48" × 48" | 24 | 48 | 2 wide (96" < 98"), 12 rows of 48" |
| Euro pallet | 47.2" × 31.5" | 30 | 60 | 3 wide (94.6" < 98"), ~10 rows of 31.5" |
| Half pallet | 48" × 20" | 48 | 96 | 4 wide (80" < 98"), 12+ rows of 20" |
Double stack assumes cargo height allows two pallet layers within the ~110" interior height. Always verify weight limits — maximum payload is ~45,000 lbs regardless of pallet count.
48-Foot vs 53-Foot Trailer — Which Should You Use?
The 53-foot trailer is the US domestic standard. The 48-foot appears in specific situations:
| Situation | Use 48-foot | Use 53-foot |
|---|---|---|
| Cross-border Canada-US freight | ✓ Common | Check provincial rules |
| US domestic full truckload | Less available | ✓ Standard |
| Dock doors built for 48-foot | ✓ Required | May not fit |
| 24 pallets or fewer | ✓ Right size | Pays for unused space |
| 25–26 pallets | Doesn't fit | ✓ Required |

28-Foot Trailer Dimensions
The 28-foot pup trailer is the workhorse of LTL doubles and urban delivery. Before counting pallets, know the actual usable interior — not just the nominal length.
| Dimension | Nominal | Usable Interior | Notes |
|---|---|---|---|
| Length | 336" | 330" | 28 ft = 336" nominal; ~330" usable after bulkhead and door swing |
| Width (exterior) | 102" | 98" | 4" lost to wall thickness on both sides |
| Height (interior) | — | 110" | Standard dry van; high-cube pup = 114" |
| Payload limit | ~24,000 lbs | ~22,000–24,000 lbs | Roughly half the payload of a 53-foot trailer; verify with carrier |
28-Foot Trailer: Pallet Count by Configuration
How you load the pallets changes the total count significantly. Here are all standard configurations for a 28-foot trailer:
| Configuration | Pallet Size | Pallets | How it works |
|---|---|---|---|
| Standard floor load ⭐ | 48×40 GMA | 14 | 2 columns × 7 rows · 48" side faces trailer length · 7×48"=336" · 2×48"=96" width with 2" clearance |
| Turned loading | 48×40 GMA | 16 | 40" side faces trailer length · 8 rows × 40" = 320" (fits in 330") · 2×48"=96" width with 2" clearance |
| Pinwheel loading | 48×40 GMA | 15–16 | Alternating pallets rotated 90° · interlocks to recover partial rows · requires consistent pallet dims |
| Double-stacked | 48×40 GMA | 28 | 2 layers of 14 · pallet height ≤48" per layer (total ≤96" incl. boards) · not all freight can stack |
| 48×48 square pallets | 48×48 | 14 | Same count as standard — 2×48"=96" width, 7 rows × 48" = 336" (exact fit) |
| Euro pallets (47×31) | 47×31 | 20 | 3 pallets across (3×31"=93") · ~10 rows × 31" = 310" · more pallets, less weight capacity per pallet |

Open Free Load Planner →When to Use a 28-Foot Trailer
A 28-foot pup trailer is not a scaled-down 53-foot. It serves specific use cases where a full-size trailer can’t or where the freight volume doesn’t justify one:
LTL doubles lane-haul
Two 28-foot pups are pulled by a single tractor on interstate LTL line-haul. The trailers are dropped and spotted independently at cross-docks, making them ideal for hub-and-spoke LTL networks.
Urban and dock-door constrained facilities
Tight urban delivery bays, older warehouse docks, and city loading zones often cannot accommodate a 53-foot trailer. A 28-foot pup can back in where a longer trailer cannot turn.
Intermodal and port transfers
Pup trailers are frequently used in port drayage and rail ramp transfers where freight is staged in smaller units before being consolidated into full-size trailers or containers.
Partial truckload shipments (PTL)
Shipments of 10–14 pallets that are too large for efficient LTL pricing but don’t fill a 53-footer can move cost-effectively as a dedicated 28-foot pup load — one trailer, one shipper, one destination.

How many pallets fit on a 28-foot trailer?
14 standard 48×40 GMA pallets floor-loaded in 2 columns of 7 rows with the 48-inch side facing the trailer length. Turning the pallets to the 40-inch orientation adds 2 more rows for a maximum of 16 floor-loaded. Double stacking where cargo permits brings the total to 28.
How many 48×40 pallets fit in a 28-foot trailer?
14 pallets — 2 wide across the 98-inch usable width (2 × 48" = 96"), 7 rows deep using 7 × 48" = 336 inches of floor length. Turning to the 40-inch orientation fits 8 rows × 2 = 16 pallets, using 320 of 330 usable inches.
What is a 28-foot pup trailer?
A 28-foot pup trailer is a short dry van trailer primarily used in LTL doubles combinations (two pups pulled by one tractor), urban delivery, and cross-dock operations. They hold roughly half the freight of a 53-foot trailer and are essential in city and dock-constrained environments where longer trailers can’t maneuver.
How does a 28-foot trailer compare to a 53-foot trailer?
A 53-foot trailer is 306 inches longer and holds 26 standard pallets versus 14 for a 28-foot, with a payload of approximately 48,000 lbs versus 22,000–24,000 lbs. Two 28-foot pups in a doubles combination carry a combined 28 pallets — 2 more than a single 53-foot trailer, but at higher operational complexity.
Does the 12-foot rule apply to 28-foot trailers?
Yes — LTL carriers apply the 12-foot linear foot capacity rule to 28-foot trailers the same way they apply it to 53-foot trailers. On a pup trailer, 5–6 pallets (3 rows of 48×40) hits the 12-foot threshold and triggers a capacity surcharge. Use the free load planner to calculate linear feet before booking.
How many linear feet is a 28-foot trailer?
Approximately 27.5 usable linear feet (330 inches). For LTL billing, each row of 48×40 pallets with the 40-inch side facing the trailer length uses 40 inches (3.33 feet), which carriers round up to 4 feet per row. A full turned-load of 8 rows occupies 320 inches — just under the full 330-inch usable floor.
How many pallets fit in two 28-foot trailers (doubles)?
28 standard pallets floor-loaded — 14 per trailer. A doubles combination therefore carries 2 more pallets than a single 53-foot trailer while allowing the trailers to be spotted and unloaded independently, which is the primary advantage in cross-dock and multi-stop LTL operations.

Frequently Asked Questions
How many pallets fit on a trailer?
It depends on trailer size. A 28-foot pup holds 14 standard 48×40 pallets floor-loaded. A 48-foot holds 24. A 53-foot holds 26. Turned loading adds 2 extra rows on any size. Double stacking doubles the count where freight and height allow.
How many pallets fit on a flatbed trailer?
A 48-foot flatbed holds 24 standard 48×40 pallets and a 53-foot flatbed holds 26 — identical to their dry van equivalents. Flatbeds have no interior height restriction, so stacking is limited by weight (48,000 lbs usable) and tie-down requirements rather than a ceiling.
Can you fit 30 pallets on a 53-foot trailer?
Yes, with pinwheel or fully turned loading. Turned loading (40" side facing trailer length) allows up to 15 rows × 2 = 30 pallets. In practice, 28–29 is the realistic maximum with pinwheel loading due to pallet size variation and load stability requirements.
What trailer size should I use?
1–9 pallets: LTL on a 53-foot. 10–14 pallets: compare LTL against a dedicated 28-foot pup. 15–26 pallets: 53-foot FTL for US domestic, 48-foot for Canada-US cross-border. 27–30 pallets: pinwheel loading on a 53-foot or a doubles combination.
Does the 12-foot rule apply on all trailer sizes?
Yes — LTL carriers apply the 12-foot rule on 28-foot, 48-foot, and 53-foot trailers equally. Three rows of 48×40 pallets (5–6 pallets) = 12 linear feet = capacity surcharge, regardless of trailer size.
How many pallets do two 28-foot trailers hold?
28 standard pallets combined — 14 per trailer, 2 more than a single 53-footer. The real advantage is operational flexibility: each trailer can be dropped and unloaded independently at cross-docks, which is why LTL carriers use doubles combinations for line-haul.
