How Big Was Jesus’s Cross, and How Much Did It Weigh?

Nobody measured Jesus’s cross, and the Gospels give neither its size nor its weight. Most modern estimates put the crossbeam, the part he probably carried, at 20 to 57 kilograms (44 to 125 pounds), and the whole cross at 80 to more than 136 kilograms (176 to more than 300 pounds). Roman crosses were generally low.

These are the published estimates and where they come from:

None of these figures comes from a measured cross. Rohault de Fleury supposed a pine cross 3 to 4 metres high weighing about 75 kilograms and worked out its volume from that. The 1986 figures rest on two older books that William Edwards, a Mayo Clinic pathologist, and his co-authors cite: Pierre Barbet’s A Doctor at Calvary and the Wycliffe Bible Encyclopedia. Leaving aside the newspaper’s figure, which gives no source, the heaviest estimate for the crossbeam is almost three times the lightest.

What do the Gospels say about the cross?

They describe what was done with the cross and leave out its measurements. Jesus went out “bearing his cross” (John 19:17), and the soldiers compelled a passer-by, “one Simon a Cyrenian,” “to bear his cross” (Mark 15:21); who he was is told in who helped Jesus carry the cross. Pilate “wrote a title, and put it on the cross,” in “Hebrew, and Greek, and Latin” (John 19:19–20), and Matthew says the soldiers “set up over his head his accusation written, This Is Jesus The King Of The Jews” (Matthew 27:37).

A few other details bear on the cross itself. When Jesus was dying, a man “filled a spunge full of vinegar, and put it on a reed, and gave him to drink” (Mark 15:36); John says the sponge was put “upon hyssop” and “to his mouth” (John 19:29). After the resurrection Thomas spoke of “the print of the nails” in Jesus’s hands (John 20:25), and the nails have their own article, how big the nails that crucified Jesus were. The apostles also called the cross a tree: “whom ye slew and hanged on a tree” (Acts 5:30), and “his own self bare our sins in his own body on the tree” (1 Peter 2:24).

How tall was Jesus’s cross?

Probably not very tall. The Catholic Encyclopedia’s article on the archaeology of the cross says that “The cross, especially in the earlier times, was generally low,” and that it was raised higher only in exceptional cases; the Roman historian Suetonius tells of Galba ordering a cross for one criminal much higher than the others and painted white. Edwards and his co-authors speak of “the customary low cross,” low enough, they argue, for a soldier’s spear 1.5 to 1.8 metres (5 to 6 feet) long to reach the chest of the man on it.

The Gospels fit a low cross without proving it: the sponge of vinegar reached Jesus’s mouth on a reed (Mark 15:36), and no Gospel says how long the reed was. The estimates for Jesus’s cross run from 3 to 4 metres (10 to 13 feet) in Rohault de Fleury’s study to 4.80 metres (15 feet 9 inches) in the old tradition; how much of the upright stood in the ground, none of them says.

How heavy was the cross Jesus carried?

By most of the estimates in the table, the crossbeam alone weighed 20 to 57 kilograms (44 to 125 pounds). The 1986 paper reasons from the whole cross to the crossbeam: “Since the weight of the entire cross was probably well over 300 lb. (136 kg), only the crossbar was carried.” It describes the crossbeam, “weighing 75 to 125 lb. (34 to 57 kg),” as “placed across the nape of the victim’s neck and balanced along both shoulders.” Zugibe, as Aleteia reports him, put the crossbeam at about 22 kilograms and the whole cross at 80 to 90; Rohault de Fleury put the whole cross at about 75 kilograms. El Debate’s almost 70 kilograms (154 pounds) for the crossbeam is the outlier, and the newspaper does not say where it comes from. Each figure depends on the size and the wood its author assumed.

Did Jesus carry the whole cross or only the crossbeam?

Probably only the crossbeam. That is the usual view, though the ancient evidence for it is thin. The Catholic Encyclopedia says the condemned man “had to carry the cross, or at least the transverse beam of it, to the place of execution,” and the 1986 paper says the upright post was “permanently located” outside the city walls, waiting for the beam. The Latin word for the beam was patibulum, and the Roman writer Seneca uses it when he lists the crosses of his day: some men, he writes, had their arms stretched on a patibulum, which his English translator renders as “a forked gibbet.”

Ruben van Wingerden, reviewing the debate in New Testament Studies in 2020, notes that the crossbeam view “is often assumed, and argued by John Granger Cook,” while Gunnar Samuelsson argued “that we grope in the dark about the exact nature” of what Jesus carried. Van Wingerden examined eight Latin texts cited for the custom and argues that “only four of these sources should be counted as referring to ‘traditional’ cross-bearing practices.” The traditional route runs about 500 to 650 metres (1,640 to 2,130 feet); how far Jesus himself carried the cross is taken up in how far Jesus carried his cross.

What shape was Jesus’s cross?

The Gospels call it a stauros. The standard Greek lexicon, Liddell and Scott’s, records that in older Greek, from Homer to Thucydides, the word meant an “upright pale or stake,” and that by the time of the Gospels it also meant a “cross, as the instrument of crucifixion”; it notes that the writer Lucian likened its form to the Greek letter T. The Romans did not keep to one design. Seneca wrote, “I see before me crosses not all alike, but differently made by different peoples,” and Josephus, describing the Roman siege of Jerusalem under Titus, says Roman soldiers nailed their prisoners to crosses “one after one way, and another after another.”

Three forms are usually distinguished:

Christian writers were describing the shape by the second century. Justin Martyr, writing in the middle of that century, describes a cross in which “the one beam is placed upright, from which the highest extremity is raised up into a horn, when the other beam is fitted on to it, and the ends appear on both sides as horns joined on to the one horn.” Irenaeus, bishop of Lyon late in the same century, writes, “The very form of the cross, too, has five extremities, two in length, two in breadth, and one in the middle, on which [last] the person rests who is fixed by the nails.” Tertullian, early in the third century, compares it to a letter: “the Greek letter Tau and our own letter T is the very form of the cross.” Those who hold to the T-shape explain the part above Jesus’s head as the title board itself.

Edwards and his co-authors weigh the two: the evidence “strongly indicates that the low Tau cross was preferred by the Romans in Palestine at the time of Christ,” but “the Latin cross and other forms also may have been used.” Samuelsson, after studying the ancient Greek, Latin and Hebrew texts, concluded that “The accounts of the death of Jesus are strikingly sparse.”

How the churches picture it

One Catholic archaeologist, Orazio Marucchi, who taught Christian archaeology in Rome, held in his 1908 article for the Catholic Encyclopedia that Jesus died on the Latin form: “It was on a cross such as this that Christ actually died, and not, as some would maintain, on a crux commissa.” He notes that this form is the one “most usually depicted on Christian monuments of all ages.”

A parish of the Russian Orthodox Church Outside of Russia explains the three bars of the cross it uses: “The top bar is the title-board which Pilate ordered to be hung in mockery over Christ’s head on the Cross,” and “The middle bar is that on which the Lord’s hands were nailed.” Of the slanted lowest bar, the footrest, it says: “There is some question of whether it was actually on the Cross of Christ, but it is acknowledged to be a necessary attribute of the Cross.”

Jehovah’s Witnesses read the evidence differently. Their official site says that “the Bible does not describe the instrument of Jesus’ death, so no one can know its shape with absolute certainty. Still, the Bible provides evidence that Jesus died, not on a cross, but on an upright stake.” They point to the meaning of stauros and to xylon, the Greek word in Acts 5:30 and 1 Peter 2:24, which they say means “wood,” “timber,” “stake,” or “tree,” and they do not use the cross in worship.

Did the cross have a seat or a footrest?

Justin and Irenaeus both mention a projection in the middle of the upright, and Justin says it is the part “on which are suspended those who are crucified.” The 1986 paper says such “a crude seat (sedile or sedulum), often was attached midway down the stipes,” the upright post. A footrest is less certain. The paper says a block for the feet was used “Only very rarely, and probably later than the time of Christ,” and the Catholic Encyclopedia says of the footrest seen in paintings “that it ever existed is very doubtful.” The Orthodox parish quoted above grants the same doubt and still keeps the footrest on its cross as “worthy of veneration.”

What wood was the cross made of?

The Gospels do not say. The only answer with a test behind it comes from relics. According to the Catholic Encyclopedia, “A microscopic examination of the fragments of the Cross scattered through the world in the form of relics reveals the fact that it was made from a pine-tree,” the finding of Rohault de Fleury’s study of 1870.

The same study answered writers who claimed that the relics of the cross, gathered together, would “be comparable in bulk to a battleship.” Rohault de Fleury catalogued every relic he could find and counted a little over 4,000,000 cubic millimetres of wood, about 4 litres. For his supposed cross of pine he reckoned 178,000,000 cubic millimetres, or 178 litres. The known relics came to less than a fortieth of one cross, and even allowing for pieces lost or overlooked, the Catholic Encyclopedia says, they would not reach a third.

What are the proportions of a Christian cross?

Crosses made for churches and homes follow customary proportions, not a measured original. The Catholic Encyclopedia describes the two classic ones: in the Latin cross “the transverse beam is usually set two-thirds of the way up the vertical,” while the Greek cross, which it calls “equilateral,” “has the transverse set half-way up the vertical.” If the old tradition’s second figure is the crossbeam, the upright was about twice its length. The three-bar cross of the Russian Orthodox parish adds the title board above the crossbeam and the slanted footrest below it.
