A logo can look perfect on a screen and still be unsuitable for a 90mm embroidered chest badge. Fine lines may close up, tiny lettering can become hard to read, and subtle colour fades cannot be recreated in thread. Understanding embroidery logo file requirements before you order helps avoid delays and gives your team a sharp, consistent finish.
For most businesses, the process is straightforward: choose your garments, upload the best version of your logo, then check the digital mock-up before production begins. You do not need to be a designer or understand stitch files to get started. What matters is supplying clear artwork and being realistic about what will remain visible once a design is stitched onto fabric.
What file do you need for an embroidered logo?
Vector artwork is the best starting point. Common vector formats include AI, EPS, SVG and editable PDF files. These files are built from shapes rather than pixels, so they can be enlarged or reduced without becoming blurred. They also give the embroidery team a cleaner reference when preparing your design for stitching.
That said, a vector file is helpful rather than essential. Many small businesses only have a PNG, JPG or a logo taken from a previous invoice, social media profile or website. Send the clearest version you have. A high-resolution PNG with a transparent background is usually a good alternative, while a sharp JPG may also work well where the logo has a solid background.
Avoid screenshots, compressed images copied from WhatsApp, and photographs of existing uniforms where possible. These can make it difficult to identify exact lines, colours and lettering. If your only available logo is low quality, it may still be usable, but the proposed embroidery may need to be simplified. The digital proof is where you can see that clearly before approving the job.
The artwork file is not the embroidery file
A logo file and an embroidery machine file are different things. Your supplied artwork is used as the reference for digitising, which is the process of mapping the design into stitch types, directions, densities and thread changes.
This is why simply changing a JPG file extension to DST, PES or EXP will not create an embroidery-ready file. Those are machine formats created after digitising. At Bolt Uniforms, customers can upload their existing logo artwork and review a mock-up without needing to arrange their own digitising or pay a separate digitising fee.
Embroidery logo file requirements that affect the finished result
The best file format helps, but design detail has the biggest effect on how an embroidered logo looks. Thread has physical width and texture. Unlike ink, it cannot reproduce every small detail visible in a digital graphic.
Lettering needs room to breathe
Small text is the most common issue with embroidered workwear logos. As a practical guide, lettering should generally be at least 4-5mm high once stitched. This can vary by font and fabric, but text below that size may lose definition, particularly on textured garments such as fleeces, piqué polo shirts and softshell jackets.
If your logo includes a company name, strapline, phone number and website address, it may be better to use only the main name on the left chest. A website or long strapline can often be placed as a larger printed design on the back, depending on the garment and the finish you want. This is not a compromise in quality - it is often the clearest way to make a uniform easy to recognise at working distance.
Bold, clean fonts usually stitch better than thin scripts, distressed typefaces or lettering with very tight spacing. Where a brand has a specific font, it can often be retained, but the smallest elements may need adjustment at the chosen logo size.
Fine lines, tiny gaps and complex shapes may need simplifying
Very thin outlines, intricate illustrations and closely packed details can merge together in thread. For example, a detailed building outline, small tools within an icon or narrow spaces inside letters may need to be thickened or removed for embroidery.
This does not mean every logo needs redesigning. A simple icon with solid areas and clear separation normally embroiders very well. The point is to judge the logo at its actual stitched size, rather than at the enlarged size shown on a computer monitor.
Where detail is central to the brand, printing may be a better choice for that artwork. Printed logos can reproduce finer lines, gradients and photographic elements, while embroidery is often preferred for its textured, durable finish on polos, sweatshirts, fleeces, jackets, gilets and caps.
Gradients and photographic effects cannot be stitched exactly
Embroidery uses individual thread colours, not blended ink. A gradient from light blue to dark blue, a shadow effect or a photograph cannot be reproduced exactly in stitch form. The design may instead need distinct colour blocks or a simplified version of the logo.
Most logos use a small number of solid colours, which is ideal for embroidery. If you have brand colour references, include them with your upload. Pantone references are useful where available, but a visual reference is often enough to select a close thread match. Thread colours can look slightly different depending on lighting and the garment colour, so check the proof with the whole garment in mind.
Choose the right logo size and position
A standard left-chest embroidery is commonly around 80-100mm wide, depending on the logo shape and garment. Taller, narrower logos may be sized by height instead. This is a sensible choice for trade polos, hoodies, jackets, fleeces and office uniform because it looks professional without overwhelming the garment.
The right size depends on both the design and where it will be worn. A simple logo may work well at 70mm wide. A logo containing readable text may need 90mm or more. On a child-sized garment, a ladies' fitted polo or a smaller gilet, the embroidery may need reducing, which can affect the smallest wording.
Back logos can be larger, although embroidery is not always the most practical option for a large back design. Bigger stitched areas can add weight, stiffness and cost, especially on lightweight T-shirts. For a large logo, team name or contact details across the back, printing is often more economical and easier to read. A mixed approach - embroidery on the chest and print on the back - works well for many businesses.
Caps, beanies and hi-vis clothing have their own considerations. Caps have limited front-panel space and seams that can affect placement. Beanies suit bold, compact logos. On hi-vis garments, branding must be positioned so it does not cover reflective tape or interfere with the garment's safety features. Tell the team how the clothing will be used if visibility compliance is a concern.
Send the supporting details with your logo
A clear logo file speeds up the artwork stage, but a few practical notes prevent assumptions. State the garment type, garment colour, preferred logo position and approximate size if you have one. If you want the same logo on polos, jackets and caps, mention this too, as each item may need a slightly different scale or placement.
If your company has previously ordered branded workwear, send a photo of the existing embroidery alongside the source logo. It is useful for showing the result you are aiming for, although the original artwork is still preferable. If you have several logo versions, label the one you want used rather than uploading a folder of unmarked files.
For larger teams, confirm whether all garments need identical branding. A catering group, for instance, may want a standard chest logo on chef jackets and aprons, with individual names or job roles added separately. A facilities company may need one logo for office staff and a more visible arrangement for site teams in hi-vis jackets.
Check the digital proof before production
The proof approval stage is your chance to check the details that matter: the correct logo version, spelling, colours, position and approximate scale on the chosen garment. Look closely at small lettering and ask whether it is genuinely readable, not merely present.
Also consider contrast. Navy thread can disappear on a black fleece, while white embroidery may show clearly but need a suitable backing on some fabrics. A proof gives a strong representation, although thread texture and screen colours mean it is not a physical sample. If something looks too small, too busy or too close in colour to the garment, request a change before approving.
Do not approve on the assumption that changes can be made once stitching starts. Production should only begin after the artwork or mock-up is approved, so taking a few minutes at this stage protects the result across every garment in the order.
A practical approach for first-time orders
Start with the best logo file you can find, even if it is not a vector. Choose a garment that suits the job, keep the chest design focused on your main logo, and use the proof to decide whether any fine detail should be simplified. This is particularly effective for smaller orders, where you need a professional result without creating a complicated branding project.
If the logo is highly detailed, do not force embroidery simply because it feels more traditional. A clean printed mark may represent your business better on T-shirts or for a large back logo, while a compact embroidered chest logo adds the durable, professional finish customers expect from workwear. The right result is the one your staff can wear confidently and your customers can recognise immediately.
