Medieval buckles up to 15mm straps
Small buckles for narrow straps up to 15 mm are often the most inconspicuous yet defining individual components of a medieval re-enactment or LARP outfit. They fasten medieval buckled shoes and lace-up boots, secure pouch flaps, hold secondary straps in place on sword belts, and add the finishing touches to costumes. Anyone putting together historically accurate equipment will quickly realise that choosing the right buckle – in terms of shape, material and historical period – determines whether the overall look is coherent or marred by an anachronistic compromise.
What makes a buckle for straps up to 15 mm special?
Small buckles for straps up to 15 mm wide are often regarded as a minor detail when putting together a costume – yet they significantly shape the appearance of shoes, bags, sword hangers and fine belts. The key difference from modern plastic snap buckles lies in their shape and material: historical pin buckles and double-bar buckles made of bronze, brass or iron correspond to archaeological findings and, together with a leather strap, create an authentic overall look that synthetic fastenings simply lack.
15 mm is considered the historically typical width for secondary straps – that is, all connecting pieces that do not form the main belt but instead secure accessories, bags or the upper material of shoes. The inner diameter of the buckle is crucial here: a buckle with an inner diameter of 15 mm fits a strap with a maximum width of 14–15 mm. If the strap is even just one millimetre too wide, it cannot be threaded through cleanly and the fastening will not function correctly. This fit should always be checked before purchase.
Fit, fitting and combination with leather straps
The correct combination of buckle and strap begins with checking the dimensions: the strap must not be wider than the inner diameter of the buckle – so for a 15 mm buckle, this means 14 to 15 mm. If the strap is chosen to be too wide, it cannot be pulled neatly through the frame and the prong will not sit correctly.
Vegetable-tanned cowhide is considered the historically correct choice. It possesses the necessary stiffness to sit securely in a buckle and, over time, develops a natural patina that enhances the authentic appearance. Fitting varies depending on the type of buckle: with pin buckles, the end of the strap is looped through, the pin is threaded through a pre-punched hole, and the protruding end of the strap is sewn or secured with a small rivet. With double-bar buckles without separate fittings, simply looping and sewing is often sufficient.
Before assembly, we recommend thoroughly oiling the leather with a suitable leather grease – this prevents brittleness and significantly extends the lifespan. In our range, you will find leather straps for medieval belts as well as leather straps made from vegetable-tanned cowhide in matching widths, designed to be combined directly with the buckles.
An overview of buckle types: Which shape is suitable for what?
Pin buckle (single-prong)
The single-bar pin buckle is the most common type: a frame with a movable pin engages with holes in the strap. Suitable for belts, bag straps and anywhere where continuous length adjustment is required. Historically documented across all eras.
Double-bar buckle
Two parallel bars allow the strap end to be securely fastened without additional fittings. Typical of shoe straps from the High and Late Middle Ages, where a secure fit is more important than stepless adjustability. Recognisable by the double frame bar.
Celtic frame buckle
Celtic buckles are characterised by an ornate frame featuring animal or interlaced motifs. They serve not only a functional purpose but are decorative elements in their own right. Particularly suitable for Celtic belts and Celtic-inspired garments.
Areas of application: Where are 15 mm buckles used?
Shoe fastenings: The most common use of small buckles is in footwear. Medieval buckled shoes and lace-up shoes often had one or more narrow straps across the instep or at the ankle – fastened with precisely such small pin or double-bar buckles. Anyone wishing to equip their Viking shoes or medieval leather shoes in a historically accurate manner will need buckles of this size.
Bags and belt pouches: On historically accurate models, bag flaps are not fastened with buttons, but with a strap and buckle. 15 mm buckles are suitable for smaller medieval bags and pouches, whose carrying straps are also made in this width. The attachment of the carrying straps to the body belt is also often achieved using narrow connecting straps with buckles.
Sword belts and weapon straps: In addition to the main belt, the sword belt features several secondary straps that stabilise the sword strap or hold the scabbard in the correct position. These auxiliary straps are narrow – 15 mm is a common width here. A suitably chosen buckle not only holds everything together visually but also fulfils a genuine safety function in re-enactment combat.
Garment fastenings: Sleeve straps, trouser ties and cloak fastenings also use narrow straps with small buckles. Particularly on garments where buttons are not historically attested, the strap-and-buckle combination is the authentic alternative.
Material and finish: bronze, brass, iron – which is historically accurate?
| Material | Suitability | Historical context |
|---|---|---|
| Bronze | Historical | Frequently found in the Early and High Middle Ages, as well as in Celtic and Germanic artefacts. Warm golden hue, corrosion-resistant, typical of replicas. |
| Brass | Historical | Widespread from the High Middle Ages onwards; cheaper to produce than bronze whilst offering a similar appearance. Slightly lighter and shinier than bronze. |
| Iron / Steel | Historical | Used mainly for utility buckles and military equipment. Darker appearance, typical of simpler items of equipment and blackened surfaces. |
| Die-cast zinc (patinated) | LARP | Cost-effective alternative for LARP and costume. Visually similar to bronze, but lighter and less durable under mechanical stress. |
The surface significantly influences the impression of authenticity: rough blackened or patinated buckles look far more authentic than polished, shiny versions, which were not standard in any period of the Middle Ages. Handcrafted bronze develops a natural patina over time, thereby gaining character. The hand-dyed leather straps from our range make a sensible addition – the dyed leather harmonises much better in colour with aged metal buckles than natural, light-coloured new leather.
Historical overview: Small buckles from the Early Middle Ages to the Renaissance
Early Middle Ages & Viking Age
Simple oval-spiked buckles made of iron or bronze dominate the range of straps. Viking-era finds reveal slender, functional forms without elaborate ornamentation. The buckles are primarily used to fasten sword scabbards and boot fastenings. Germanic and Celtic variants differ in their use of animal motifs.
High Middle Ages
D-shaped and rectangular buckles become widespread on sword hangers and shoe straps. The shapes become more uniform, the workmanship more precise. Brass appears alongside bronze as a common material. Shoe buckles begin to be used as design elements beyond their purely functional purpose.
Late Middle Ages
Shoe buckles develop into status symbols: more elaborate shapes, engraved frames and gilding for wealthy wearers. The straps on bags and sword hangers become more delicate. Small buckles can now be found almost everywhere on the garment – from the cloak fastening to the trouser leg.
Renaissance
The design language becomes more elaborate; fittings and buckles are designed as a decorative ensemble. Small buckles are increasingly found on sleeves and bodices. The width of straps continues to decrease in the area of garment fastenings – though 10 to 15 mm remains a common standard width for functional fasteners.

Frequently asked questions
You need a buckle with an internal diameter of at least 15 mm. The strap should be no wider than the internal diameter of the buckle so that it can be threaded through cleanly and the pin functions correctly. If the strap is too wide, it cannot be pulled through the frame without issues.
A pin buckle has a movable pin that engages with holes in the strap, allowing for continuous length adjustment – ideal for belts and bag straps. A double-bar buckle has two parallel bars without a prong: the end of the strap is firmly threaded through and sewn or riveted, resulting in a stable, non-adjustable connection. Double-bar buckles are typical of shoe straps from the High and Late Middle Ages.
Bronze is the historically best-documented material for small buckles from the Early to the Late Middle Ages. From the High Middle Ages onwards, brass also became common. Iron and steel were used primarily for simple work buckles and military equipment. For re-enactment purposes, cast bronze is considered the best choice; patinated surfaces look more authentic than polished ones.
Yes, 15 mm buckles are historically typical for shoe straps. Medieval buckled shoes and lace-up shoes often had one or two narrow straps across the instep or at the ankle, which were fastened with small pin or double-bar buckles of this size. Vegetable-tanned cowhide is the historically correct choice of strap material.
Thread the end of the strap through the frame of the buckle so that the pin lies flat against the surface of the strap. The short end of the strap that protrudes is then either secured with a small rivet or sewn in place. Before fitting, it is advisable to oil the leather so that it remains supple and does not fray at the cut edges. With double-bar buckles, the end is threaded through both bars and then secured.
