A pallet lorry that is only slightly wrong on fork width can cause regular problems on the floor. It may not enter the pallet cleanly, it may catch on pallet runners, or it may leave operators working around the equipment instead of using it properly. If you need to measure pallet lorry fork width, the job is straightforward, but only if you are clear about which width you actually need.
For trade buyers and maintenance teams, that distinction matters. Some suppliers list overall width across both forks, others refer to the width of each individual fork, and some buyers really need the gap between the forks to match a particular pallet or application. Measuring the wrong point can leave you with the wrong lorry or the wrong replacement assembly.
What does pallet lorry fork width mean?
In day-to-day buying, pallet lorry fork width can mean three different things. The first is the width of one fork blade. The second is the outside width across both forks. The third is the inside gap between the forks. All three can be relevant, depending on whether you are replacing parts, checking pallet compatibility or comparing lorry specifications.
This is where most mistakes happen. A standard pallet lorry may be sold by overall fork width, such as 520mm or 685mm, because that helps buyers match the lorry to standard pallet sizes. But if you are ordering a fork, a wheel bracket, or checking wear and clearance, the individual fork width is usually the figure that matters.
Before you measure pallet lorry fork width
Start with the lorry unloaded and parked on level ground. Lower the forks fully so they are stable and easy to access. If the lorry has seen heavy use, clear away debris, shrink wrap residue and dirt around the fork edges. Built-up material can throw out a measurement more than you might expect, especially if you are checking for a close fit.
Use a steel rule or tape measure with clear millimetre markings. For parts work, a vernier caliper is better if you need a more exact reading on one fork blade. In most warehouse and workshop settings, millimetres are the practical standard, and that is how most UK product specifications are listed.
It is also worth checking whether the forks are straight before you start. A bent fork or twisted tip can make the width appear inconsistent from front to back. If the lorry has taken impact damage, measure in more than one place and note any variation.
How to measure pallet lorry fork width correctly
If you need the individual fork width, measure straight across the top of one fork blade from one outside edge to the other. Take the reading on the main straight section, not on a tapered or worn tip. Repeat on the second fork if the lorry is older, because wear or repair work can leave small differences between sides.
If you need the overall fork width, measure from the outer edge of the left fork to the outer edge of the right fork. This is often the figure used when selecting a standard or narrow pallet lorry. Take the reading at a square section of the forks where the spacing is consistent.
If you need the inside gap, measure from the inner edge of one fork to the inner edge of the other. This is less commonly used in product titles, but it can be useful if you are checking suitability for a specific stillage, pallet base or handling fixture.
Measure at more than one point
On a well-used pallet lorry, do not rely on one measurement alone. Check near the fork heel, around the midpoint and closer to the tip. The spacing should normally remain consistent. If it does not, the lorry may be damaged, modified or worn enough to affect handling.
That matters for more than specification. Uneven spacing can make pallet entry awkward, put load stress where it should not be, and create a poor fit for replacement components.
Common pallet lorry widths in practice
Many buyers are dealing with two broad overall width categories. Narrow pallet lorries are often around 520mm overall, while standard wide pallet lorries are commonly around 685mm overall. Those figures are widely used because they suit common pallet formats and loading routines.
Even so, there is no benefit in assuming. Imported lorries, older models and specialist units can vary. Individual fork widths can also differ between manufacturers, even where the overall width looks familiar. That is why a quick measurement is usually safer than working from memory or visual comparison.
When standard sizes are not enough
If your operation handles euro pallets, UK pallets, bespoke skids or stillages, width selection can become more application-specific. A lorry that works well for one pallet format may be awkward for another. In mixed environments, buyers sometimes choose a standard width for general use and keep a narrower unit for confined access or non-standard loads.
That is a practical decision rather than a universal rule. The right choice depends on the pallets in circulation, aisle space, operator habits and whether the lorry is being used on vehicles, in production areas or at goods-in.
Why accurate measurement matters before buying
If you are replacing a pallet lorry, the wrong width can affect daily handling immediately. Operators will notice if the forks do not line up well with pallet openings, especially where speed matters and loads are repetitive. Small inefficiencies add up quickly in dispatch, replenishment and internal movement tasks.
If you are ordering parts, accuracy matters even more. A fork assembly, steer wheel bracket or related component may only fit one specific fork profile or width arrangement. Getting close is not enough if bolt centres, clearances or frame dimensions depend on the original size.
This is also where a dependable supplier helps. A specification sheet is useful, but clear support is often what prevents returns, delays and downtime when measurements are not obvious from the unit itself.
Mistakes buyers and maintenance teams often make
The most common mistake is measuring the total width and assuming that figure applies to each fork. The second is measuring at the tips, where wear or taper can alter the result. The third is forgetting that an older lorry may have been repaired with non-original parts.
There is also a tendency to focus only on width and ignore fork length. In practice, both dimensions work together. A lorry with the right width but the wrong fork length may still be unsuitable for the load or pallet type. Similarly, wheel type, lowered height and capacity can all affect whether the lorry is genuinely fit for the application.
That is why a quick check of width should sit within a broader look at the lorry specification. If the equipment is already causing handling issues, width may be the visible symptom rather than the whole problem.
Measuring for replacement forks or parts
When you are measuring for parts rather than a complete lorry, record more than one dimension. Note the individual fork width, overall width, fork length and any visible part numbers or ID plates. If the lorry brand and model are readable, record those as well.
Photographs can also help when passing information to a supplier or procurement colleague, even if the final order will still be based on measurements. A clear image of the fork profile, wheel area and lorry body can reduce back-and-forth and speed up identification.
Where the lorry is heavily worn, it is sensible to compare the measured dimension with any manufacturer marking if one remains visible. Wear can reduce thickness or alter edges enough to confuse a basic tape measurement. In those cases, practical judgement matters. You are trying to identify the original working size, not just the worn condition on the day.
When fork width affects safety and handling
Fork width is not just a buying detail. If a pallet lorry is a poor fit for the pallets being used, operators may force entry, approach at poor angles or drag loads in ways that increase wear and risk. That can damage pallets, shorten wheel life and create avoidable strain during manual handling.
A badly matched width also affects control. Loads that are not properly supported across the pallet can feel unstable, especially on uneven surfaces or during turns. In a busy warehouse or workshop, those small handling compromises tend to become accepted as normal until equipment is reviewed properly.
The practical fix is often simple. Measure the current lorry accurately, compare that against the pallets or load carriers in use, and decide whether the issue is wear, damage, wrong specification or a change in operation.
A simple measuring routine that saves time
For most buyers, the best approach is to take four readings and write them down in millimetres: individual fork width, overall width across both forks, inside gap and fork length. Add the lorry make, model and capacity if available. That gives you enough information for most purchasing and parts enquiries without guesswork.
If the lorry is in constant use and downtime is costly, check the measurements before failure forces the issue. It is much easier to source the right replacement when you are planning the job than when the unit is already off the floor.
A few minutes with a tape measure now usually costs less than a returned order, a delayed repair or a pallet lorry that never quite fits the work it is meant to do.
