What is a Ell and a Toise?

The Ell is an historical unit of length, primarily used for measuring cloth and textiles. Its exact length varied considerably depending on the region, country, and time period, making it a non-standardized unit overall, though often legally defined within specific jurisdictions.

It is generally understood to have originated from the length of the arm or forearm, similar to the cubit. The name itself derives from the Proto-Germanic word *alinō, meaning "forearm".

Common historical values demonstrate this variability:

  • English Ell: Traditionally 45 inches (1.25 yards, exactly 1.143 meters). This was the most common ell in England, particularly for measuring imported Flemish cloth.
  • Scottish Ell: Approximately 37.06 inches (about 0.941 meters), based on the standard Scottish inch.
  • Flemish (or Brabant) Ell: Approximately 27 inches (about 0.686 meters). Widely used in the Low Countries, a major center for textile production.
  • French Ell (Aune): Varied, but often around 46.77 inches (about 1.188 meters) in Paris. The aune itself had different lengths in different French regions.
  • Polish Ell (Łokieć): Approximately 22.7 inches (about 0.576 meters).
  • Swedish Ell (Aln): Approximately 23.3 inches (about 0.593 meters).

The Toise is an historical French unit of length, used extensively before the adoption of the metric system. It was legally defined as 6 pieds du roi (French royal feet).

Based on the standard established for the pied du roi, the Toise equates to:

  • Exactly 1.94903631 meters (m) (based on the 1799 definition of the meter relative to the standard Toise bar)
  • Approximately 6.395 English feet (ft)
  • Approximately 76.73 English inches (in)

The Toise was further subdivided:

  • 1 Toise = 6 Pieds (French feet)
  • 1 Toise = 72 Pouces (French inches)
  • 1 Toise = 864 Lignes (French lines)

Note: The Ell is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Toise belongs to the imperial/US customary system.

History of the Ell and Toise

The ell was a fundamental unit for the textile trade across Europe, flourishing from the medieval period through the early modern era and into the 19th century. Its origins likely lie in anthropomorphic measurements related to the arm, similar to the cubit.

The lack of a universal standard led to numerous regional variations. Different cities, guilds, or nations established their own "standard" ell, often physically represented by a metal rod kept by authorities. This variation could sometimes be a source of trade disputes but also reflected local manufacturing and trade practices.

The English ell of 45 inches (longer than the standard English yard of 36 inches) became particularly well-established, possibly to account for shrinkage or to provide a customary "bonus" measure when selling cloth.

With the rise of standardized measurement systems like the Imperial system (promoting the yard) and especially the Metric system (introducing the meter), the ell gradually became obsolete during the 18th and 19th centuries. Legal reforms in many countries formally abolished it in favor of metric units.

The Toise was a fundamental unit of length in France for centuries, used in various fields from the Middle Ages through the Ancien Régime and into the early post-revolutionary period. Its name derives from the Latin tensa, meaning "stretched (arms)", suggesting an origin related to fathom.

Standardization was crucial. The primary standard became the Toise du Châtelet, an iron bar embedded in the wall of the Grand Châtelet fortress in Paris. In 1668, this standard was physically copied by Jean Picard and used for geodetic surveys. Later, a copy known as the Toise du Pérou (or Toise de l'Académie) became the official reference standard for French length measurements. This specific bar was physically used in the famous French Geodesic Missions to Peru (1735–1744) and Lapland (1736–1737), which aimed to measure the length of a degree of latitude near the equator and the Arctic Circle, respectively.

These measurements, based on the Toise, were instrumental in determining the shape of the Earth and ultimately provided the basis for the definition of the meter. The meter was initially defined in the 1790s as one ten-millionth of the distance from the North Pole to the Equator along the meridian passing through Paris, a distance calculated from the geodetic surveys performed using the Toise standard.

The Toise was officially replaced by the meter following the French Revolution and the establishment of the metric system in France, formally adopted in 1799.

Common Uses for ells and toise

Explore the typical applications for both Ell (imperial/US) and Toise (imperial/US) to understand their common contexts.

Common Uses for ells

The ell is now obsolete but was historically crucial for:

  • Textile Trade: Its primary and defining use was measuring and selling lengths of cloth (wool, linen, silk, etc.). Cloth was often priced and sold "by the ell".
  • Tailoring and Dressmaking: Used by artisans creating garments.
  • Mercantile Records: Appears frequently in historical merchant accounts, inventories, customs documents, and trade records. Understanding the local ell is vital for interpreting these economic historical sources.
  • Land Measurement (Rarely): In some specific, localized contexts, an ell might have been used for land, but this was uncommon compared to units like the rod or chain.
  • Literature and Culture: Referenced in historical texts, literature, and idioms (e.g., "Give him an inch, and he'll take an ell").

Common Uses for toise

The Toise is now obsolete but was historically essential for:

  • Land Surveying: Measuring land areas, property boundaries, and distances for cartography.
  • Architecture and Civil Engineering: Designing and constructing buildings, bridges, canals, roads, and fortifications (notably by Vauban). Dimensions of major historical French structures were often specified in Toise.
  • Military Engineering: Laying out fortifications, measuring artillery ranges.
  • Geodesy and Scientific Measurement: Serving as the standard unit for precise scientific measurements, particularly in astronomy and the crucial 18th-century geodetic surveys that measured the Earth.
  • Craftsmanship: Used in various trades requiring length measurements.

Frequently Asked Questions

Questions About Ell (ell)

How long is an Ell?

There is no single fixed length for the ell; it varied significantly by location and time. Some key examples include:

  • English Ell: 45 inches (1.143 m)
  • Scottish Ell: ~37 inches (~0.94 m)
  • Flemish Ell: ~27 inches (~0.69 m)
  • French Aune (Ell): ~47 inches (~1.19 m) Always check the context (region and era) when encountering a measurement in ells. The English ell of 45 inches is often assumed in English-language historical contexts unless otherwise specified.

How does the Ell compare to a Yard?

The English ell (45 inches) is exactly 1.25 times longer than the standard yard (36 inches). However, other ells could be shorter (like the Flemish ell) or have different relationships to the local yard equivalent.

Is the Ell related to the Elbow or Arm?

Yes, the name "ell" derives from Proto-Germanic *alinō ("forearm"), cognate with Latin ulna and Greek ōlénē, all referring to the forearm or elbow. This strongly suggests an origin based on the length of the human arm, similar to the cubit. However, the standardized lengths adopted for trade were often considerably longer than a literal forearm.

Why did the Ell length vary so much?

The variation stemmed from:

  • Lack of Universal Standards: Before the metric system, measurement standards were highly localized.
  • Regional Customs: Different areas developed their own traditional lengths based on local needs and practices.
  • Trade Protectionism: Sometimes, variations were maintained deliberately by guilds or cities.
  • Evolution Over Time: The definition could change even within the same region over centuries.

Is the Ell an SI unit?

No, the ell is not part of the International System of Units (SI). It is an historical, customary unit belonging to various pre-metric systems. The corresponding SI unit for length is the meter (m).

Is the Ell still used today?

No, the ell is obsolete and is not used for any standard commercial, scientific, or practical measurements today. Its use was superseded primarily by the yard (in Imperial/US customary systems) and the meter (in the metric system). Its relevance is now purely historical.

About Toise (toise)

How long is a Toise?

The standard French Toise is defined as 6 pieds du roi (French royal feet). This corresponds to:

  • Exactly 1.94903631 meters
  • Approximately 6.395 English feet

How does the Toise compare to a Meter?

  • 1 Toise ≈ 1.949 meters
  • 1 Meter ≈ 0.513 Toise The Toise was the historical standard upon which the original definition of the meter was based through geodetic surveys.

What were the subdivisions of the Toise?

The Toise was divided based on the French foot (pied du roi):

  • 1 Toise = 6 Pieds
  • 1 Pied = 12 Pouces (inches)
  • 1 Pouce = 12 Lignes (lines) Therefore, 1 Toise = 72 pouces = 864 lignes.

Is the Toise an SI unit?

No, the Toise is not an SI unit. It is a traditional unit from the pre-metric French system (Mesures usuelles). The SI base unit for length is the meter (m).

Is the Toise still used today?

No, the Toise is obsolete and not used in modern measurements. It was legally replaced by the meter in France and elsewhere. Its significance today is purely historical, particularly in the context of historical architecture, engineering, surveying, and the scientific history leading to the metric system.
